The Hamiltonian term is treated as an integrating factor by forward and backward Fourier transforms, which are here carried out classically. This split allows us to avoid higher-order time integration schemes, to apply a first-order explicit time stepping for the remaining nonlinear NLSE term in a variational algorithm block, and thus to avoid numerical instabilities. We demonstrate that the analytical solution is reproduced with a small root mean square error for a long time interval over which a nonlinear soliton propagates significantly forward in space while keeping its shape. We analyze the accuracy and complexity of the quantum algorithm, the expressibility of the ansatz circuit and compare it with classical approaches. Furthermore, we investigate the influence of algorithm parameters on the accuracy of the results, including the temporal step width and the depth of the quantum circuit.</jats:p>"}],"publication":"Scientific Reports","issue":"1","doi":"10.1038/s41598-025-05660-3","article_number":"23478","language":[{"iso":"eng"}],"date_updated":"2025-09-12T10:57:22Z","publication_status":"published","intvolume":"        15","title":"Numerical solution of nonlinear Schrödinger equation by a hybrid pseudospectral-variational quantum algorithm","year":"2025","publication_identifier":{"issn":["2045-2322"]},"author":[{"id":"79191","first_name":"Nikolas","last_name":"Köcher","full_name":"Köcher, Nikolas"},{"full_name":"Rose, Hendrik","first_name":"Hendrik","orcid":"0000-0002-3079-5428","last_name":"Rose","id":"55958"},{"full_name":"Bharadwaj, Sachin S.","last_name":"Bharadwaj","first_name":"Sachin S."},{"full_name":"Schumacher, Jörg","last_name":"Schumacher","first_name":"Jörg"},{"id":"27271","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","full_name":"Schumacher, Stefan"}]},{"date_updated":"2025-09-12T11:02:33Z","publication_status":"published","intvolume":"        23","year":"2025","title":"Optically and remotely controlling localization of exciton-polariton condensates in a potential lattice","publication_identifier":{"issn":["2331-7019"]},"author":[{"full_name":"Ai, Qiang","first_name":"Qiang","last_name":"Ai"},{"last_name":"Wingenbach","first_name":"Jan","full_name":"Wingenbach, Jan","id":"69187"},{"full_name":"Yang, Xinmiao","last_name":"Yang","first_name":"Xinmiao"},{"full_name":"Wei, Jing","last_name":"Wei","first_name":"Jing"},{"first_name":"Zaharias","last_name":"Hatzopoulos","full_name":"Hatzopoulos, Zaharias"},{"full_name":"Savvidis, Pavlos G.","last_name":"Savvidis","first_name":"Pavlos G."},{"id":"27271","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","first_name":"Stefan"},{"full_name":"Ma, Xuekai","last_name":"Ma","first_name":"Xuekai","id":"59416"},{"first_name":"Tingge","last_name":"Gao","full_name":"Gao, Tingge"}],"doi":"10.1103/physrevapplied.23.024029","article_number":"024029","language":[{"iso":"eng"}],"issue":"2","publication":"Physical Review Applied","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"230"},{"_id":"35"},{"_id":"27"}],"date_created":"2025-09-12T11:01:17Z","status":"public","user_id":"16199","volume":23,"_id":"61249","publisher":"American Physical Society (APS)","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"chicago":"Ai, Qiang, Jan Wingenbach, Xinmiao Yang, Jing Wei, Zaharias Hatzopoulos, Pavlos G.

Anisotropic organic single‐crystalline materials can induce abundant SOC phenomenon due to their flexible tunability of molecular geometries, however, the intrinsic relationship between molecular geometries/orientations in 3D space and photonic SOC is lacking. In this study, we design two kinds of 2D organic polymorphs for the construction of organic microcavities to investigate the structure‐performance relationships. In two polymorphic microcavities, two distinctive photonic SOC phenomena are observed regardless of the in‐plane anisotropy of organic polymorphs. Theoretical analysis indicates that the photonic SOC strength is strongly influenced by the synergies between the crystal anisotropy and the tilted collective molecular transition dipole moment. Our results uncover the correlation mechanism between the structure of molecules and photonic SOC and open an avenue to engineer complex photonic SOC by use of organic microstructures towards the development of diverse integrated photonic devices.</jats:p>","lang":"eng"}],"date_created":"2025-12-04T12:33:48Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"}],"year":"2025","title":"Molecular Orientation‐Dependent Photonic Spin–Orbit Coupling in Organic Microcavities Filled with 2D Polymorphic Crystals","status":"public","author":[{"first_name":"Ying","last_name":"Ji","full_name":"Ji, Ying"},{"first_name":"Xuekai","last_name":"Ma","full_name":"Ma, Xuekai","id":"59416"},{"full_name":"Huang, Han","last_name":"Huang","first_name":"Han"},{"full_name":"Deng, Yibo","last_name":"Deng","first_name":"Yibo"},{"full_name":"Wang, Pingyang","last_name":"Wang","first_name":"Pingyang"},{"last_name":"Long","first_name":"Teng","full_name":"Long, Teng"},{"last_name":"Li","first_name":"Yuan","full_name":"Li, Yuan"},{"full_name":"Zhao, Ruiyang","first_name":"Ruiyang","last_name":"Zhao"},{"first_name":"Yunfei","last_name":"Li","full_name":"Li, Yunfei"},{"full_name":"An, Cunbin","first_name":"Cunbin","last_name":"An"},{"id":"27271","last_name":"Schumacher","first_name":"Stefan","orcid":"0000-0003-4042-4951","full_name":"Schumacher, Stefan"},{"full_name":"Gu, Chunling","first_name":"Chunling","last_name":"Gu"},{"full_name":"Liao, Bo","first_name":"Bo","last_name":"Liao"},{"first_name":"Hongbing","last_name":"Fu","full_name":"Fu, Hongbing"},{"last_name":"Liao","first_name":"Qing","full_name":"Liao, Qing"}],"publication_identifier":{"issn":["1863-8880","1863-8899"]},"date_updated":"2025-12-04T12:34:45Z","publication_status":"published","article_number":"e01874","_id":"62867","language":[{"iso":"eng"}],"publisher":"Wiley","doi":"10.1002/lpor.202501874","user_id":"16199"},{"publisher":"AIP Publishing","_id":"62862","user_id":"16199","volume":127,"status":"public","citation":{"chicago":"Ai, Qiang, Xuekai Ma, Franziska Barkhausen, Xiaokun Zhai, Chunzi Xing, Xinmiao Yang, Peilin Wang, et al. “Tuning Polariton Vortices in an Asymmetric Ring Potential.” <i>Applied Physics Letters</i> 127, no. 12 (2025). <a href=\"https://doi.org/10.1063/5.0287076\">https://doi.org/10.1063/5.0287076</a>.","short":"Q.

Here, a novel nucleophilic‐attack n‐doping mechanism is unveiled that achieves exceptionally high conductivity in doped OSC films and demonstrates broad applicability across OSCs.

The investigation reveals that the n‐BuLi anion interacts with electron‐deficient units in OSCs, generating a carbanion that facilitates efficient electron transfer for n‐doping. This mechanism is further validated across diverse fullerenes, polymeric, and small molecule OSCs, and is extendable to other high‐performance dopants such as tert‐Butyllithium (tert‐BuLi) and sodium ethoxide (NaOEt).

Going beyond isolated EPs, here we report on the existence of exceptional rings (ERs) in planar optical resonators with specific form of circular dichroism and TE-TM splitting. Such exceptional rings possess intriguing topologies as discussed earlier for condensed matter systems, but they remain virtually unexplored in presence of nonlinearity, for which our photonic platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain) is introduced, the linear ER splits into two concentric ERs, with the larger-radius ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime, we present a rigorous analysis of spectral topology and report enhanced and adjustable perturbation response in the nonlinear regime. Whereas certain features are specific to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced perturbation response are generic and equally relevant to a broad class of other nonlinear non-Hermitian systems, providing a universal framework for engineering ERs and EPs in nonlinear non-Hermitian systems."}],"citation":{"bibtex":"@article{Wingenbach_Ares Santos_Ma_Sperling_Schumacher_2025, title={Sensitivity and Topology of Exceptional Rings in Nonlinear Non-Hermitian Planar Optical Microcavities}, DOI={<a href=\"https://doi.org/10.48550/ARXIV.2507.07099\">10.48550/ARXIV.2507.07099</a>}, journal={Arxiv}, publisher={Arxiv}, author={Wingenbach, Jan and Ares Santos, Laura  and Ma, Xuekai and Sperling, Jan and Schumacher, Stefan}, year={2025} }","ama":"Wingenbach J, Ares Santos L, Ma X, Sperling J, Schumacher S.

We explicitly demonstrate the theoretical generation of linear cluster states with substantial numbers of entangled photonic qubits in full microscopic numerical simulations. The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections. The specific results shown in the present work illustrate that with controlled minimization of losses and realistic system parameters for quantum-dot type systems, useful linear cluster states of significant lengths can be generated in the calculations, discussing the possibility of scalability for quantum information processing endeavors.</jats:p>","lang":"eng"}],"date_created":"2025-09-12T11:08:59Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"},{"_id":"623"}],"status":"public","_id":"61251","publisher":"AIP Publishing","user_id":"16199","volume":1,"citation":{"bibtex":"@article{Bauch_Köcher_Heinisch_Schumacher_2024, title={Time-bin entanglement in the deterministic generation of linear photonic cluster states}, volume={1}, DOI={<a href=\"https://doi.org/10.1063/5.0214197\">10.1063/5.0214197</a>}, number={3036110}, journal={APL Quantum}, publisher={AIP Publishing}, author={Bauch, David and Köcher, Nikolas and Heinisch, Nils and Schumacher, Stefan}, year={2024} }","ama":"Bauch D, Köcher N, Heinisch N, Schumacher S.

This allows the generation of high-quality single photons without the need of complex laser stray light suppression or careful spectral filtering. In the present work, we extend this promising method to quantum emitters, specifically semiconductor quantum dots, inside a resonant optical cavity. A significant advantage of the SUPER scheme is identified in that it eliminates re-excitation of the quantum emitter by suppressing photon emission during the excitation cycle. This, in turn, leads to almost ideal single-photon purity, overcoming a major factor typically limiting the quality of photons generated with quantum emitters in high-quality cavities. We further find that for cavity-mediated biexciton emission of degenerate photon pairs, the SUPER scheme leads to near-perfect biexciton initialization with very high values of polarization entanglement of emitted photon pairs.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>"}],"publication":"Physical Review Research","issue":"1","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"type":"journal_article","date_created":"2025-09-12T11:16:31Z","intvolume":"         6","date_updated":"2025-09-12T11:18:05Z","publication_status":"published","author":[{"id":"90283","full_name":"Heinisch, Nils","last_name":"Heinisch","orcid":"0009-0006-0984-2097","first_name":"Nils"},{"first_name":"Nikolas","last_name":"Köcher","full_name":"Köcher, Nikolas","id":"79191"},{"full_name":"Bauch, David","first_name":"David","last_name":"Bauch"},{"full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271"}],"publication_identifier":{"issn":["2643-1564"]},"year":"2024","title":"Swing-up dynamics in quantum emitter cavity systems: Near ideal single photons and entangled photon pairs","doi":"10.1103/physrevresearch.6.l012017","language":[{"iso":"eng"}],"article_number":"L012017"},{"citation":{"mla":"Schneider, Tobias, et al. “Topological Edge and Corner States in Coupled Wave Lattices in Nonlinear Polariton Condensates.” <i>Nanophotonics</i>, vol. 13, no. 4, Walter de Gruyter GmbH, 2024, pp. 509–18, doi:<a href=\"https://doi.org/10.1515/nanoph-2023-0556\">10.1515/nanoph-2023-0556</a>.","ama":"Schneider T, Gao W, Zentgraf T, Schumacher S, Ma X.

In the present work, we report on topological edge states in double-wave (DW) chains, which can be described by a generalized Aubry-André-Harper (AAH) model. For the specific system of a driven-dissipative exciton polariton system we show that in such potential chains, different types of edge states can form. For resonant optical excitation, we further find that the optical nonlinearity leads to a multistability of different edge states. This includes topologically protected edge states evolved directly from individual linear eigenstates as well as additional edge states that originate from nonlinearity-induced localization of bulk states. Extending the system into two dimensions (2D) by stacking horizontal DW chains in the vertical direction, we also create 2D multi-wave lattices. In such 2D lattices multiple Su–Schrieffer–Heeger (SSH) chains appear along the vertical direction. The combination of DW chains in the horizonal and SSH chains in the vertical direction then results in the formation of higher-order topological insulator corner states. Multistable corner states emerge in the nonlinear regime.</jats:p>"}],"date_created":"2025-09-12T11:19:22Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"type":"journal_article","author":[{"full_name":"Schneider, Tobias","first_name":"Tobias","last_name":"Schneider"},{"first_name":"Wenlong","last_name":"Gao","full_name":"Gao, Wenlong","id":"78853"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf","id":"30525"},{"id":"27271","last_name":"Schumacher","first_name":"Stefan","orcid":"0000-0003-4042-4951","full_name":"Schumacher, Stefan"},{"full_name":"Ma, Xuekai","first_name":"Xuekai","last_name":"Ma","id":"59416"}],"publication_identifier":{"issn":["2192-8614"]},"year":"2024","title":"Topological edge and corner states in coupled wave lattices in nonlinear polariton condensates","intvolume":"        13","date_updated":"2025-09-12T11:22:41Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1515/nanoph-2023-0556"},{"_id":"61257","publisher":"American Physical Society (APS)","volume":6,"user_id":"16199","status":"public","citation":{"apa":"Wingenbach, J., Schumacher, S., &#38; Ma, X.

Here, we investigate spectral topology and EPs in systems with significant nonlinearity, exemplified by a nonequilibrium exciton-polariton condensate. With the possibility to control loss and gain and nonlinearity by optical means, this system allows for a comprehensive analysis of the interplay of nonlinearities (Kerr type and saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally shifted in parameter space by the saturable gain, but we also observe intriguing rotations and intersections of Riemann surfaces and find nonlinearity-enhanced sensing capabilities. With this, our results illustrate the potential of tailoring spectral topology and related phenomena in non-Hermitian systems by nonlinearity.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>","lang":"eng"}]},{"abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Thermal stability is crucial for doped organic semiconductors (OSCs) and their applications in organic thermoelectric (OTE) devices.

We explicitly demonstrate the theoretical generation of linear cluster states with substantial numbers of entangled photonic qubits in full microscopic numerical simulations. The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections. The specific results shown in the present work illustrate that with controlled minimization of losses and realistic system parameters for quantum-dot type systems, useful linear cluster states of significant lengths can be generated in the calculations, discussing the possibility of scalability for quantum information processing endeavors.</jats:p>"}],"date_created":"2025-12-04T12:35:53Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"27"},{"_id":"429"},{"_id":"230"},{"_id":"623"}],"year":"2024","title":"Time-bin entanglement in the deterministic generation of linear photonic cluster states","publication_identifier":{"issn":["2835-0103"]},"author":[{"first_name":"David","last_name":"Bauch","full_name":"Bauch, David"},{"full_name":"Köcher, Nikolas","last_name":"Köcher","first_name":"Nikolas","id":"79191"},{"orcid":"0009-0006-0984-2097","last_name":"Heinisch","first_name":"Nils","full_name":"Heinisch, Nils","id":"90283"},{"full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271"}],"date_updated":"2025-12-05T13:55:00Z","publication_status":"published","intvolume":"         1","article_number":"036110","language":[{"iso":"eng"}],"doi":"10.1063/5.0214197","citation":{"mla":"Bauch, David, et al. “Time-Bin Entanglement in the Deterministic Generation of Linear Photonic Cluster States.” <i>APL Quantum</i>, vol. 1, no. 3, 036110, AIP Publishing, 2024, doi:<a href=\"https://doi.org/10.1063/5.0214197\">10.1063/5.0214197</a>.","bibtex":"@article{Bauch_Köcher_Heinisch_Schumacher_2024, title={Time-bin entanglement in the deterministic generation of linear photonic cluster states}, volume={1}, DOI={<a href=\"https://doi.org/10.1063/5.0214197\">10.1063/5.0214197</a>}, number={3036110}, journal={APL Quantum}, publisher={AIP Publishing}, author={Bauch, David and Köcher, Nikolas and Heinisch, Nils and Schumacher, Stefan}, year={2024} }","ama":"Bauch D, Köcher N, Heinisch N, Schumacher S.
