However, the tunneling dynamics in solids, especially nonadiabatic tunneling, has not yet been fully understood. Here, we study the sub-cycle resolved strong-field tunneling dynamics in solids via a complex saddle-point method. We compare the instantaneous momentum at the moment of tunneling and the tunneling distances over a range of Keldysh parameters. Our results demonstrate that for nonadiabatic tunneling, tunneling ionization away from Γ point is possible. When this happens the electron has a nonzero initial velocity when it emerges in the conduction band. Moreover, consistent with atomic tunneling, a reduced tunneling distance as compared to the quasi-static case is found. Our results provide remarkable insight into the basic physics governing the sub-cycle electron tunneling dynamics with significant implications for understanding subsequent strong-field nonlinear phenomena in solids.</jats:p>"}],"issue":"9","publication":"Optics Express","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"date_created":"2024-07-15T09:25:30Z","status":"public","user_id":"16199","volume":32,"publisher":"Optica Publishing Group","_id":"55264","citation":{"chicago":"Yang, Shidong, Xiwang Liu, Hongdan Zhang, Xiaohong Song, Ruixin Zuo, Torsten Meier, and Weifeng Yang. “Sub-Cycle Strong-Field Tunneling Dynamics in Solids.” <i>Optics Express</i> 32, no. 9 (2024). <a href=\"https://doi.org/10.1364/oe.521207\">https://doi.org/10.1364/oe.521207</a>.","short":"S.

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.

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>","lang":"eng"}],"publication":"Physical Review Research","issue":"1","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"date_created":"2025-09-12T11:16:31Z","publication_status":"published","date_updated":"2025-09-12T11:18:05Z","intvolume":"         6","year":"2024","title":"Swing-up dynamics in quantum emitter cavity systems: Near ideal single photons and entangled photon pairs","author":[{"id":"90283","last_name":"Heinisch","first_name":"Nils","orcid":"0009-0006-0984-2097","full_name":"Heinisch, Nils"},{"id":"79191","last_name":"Köcher","first_name":"Nikolas","full_name":"Köcher, Nikolas"},{"last_name":"Bauch","first_name":"David","full_name":"Bauch, David"},{"id":"27271","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","first_name":"Stefan","last_name":"Schumacher"}],"publication_identifier":{"issn":["2643-1564"]},"doi":"10.1103/physrevresearch.6.l012017","article_number":"L012017","language":[{"iso":"eng"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142; TP C09: Ideale Erzeugung von Photonenpaaren für Verschränkungsaustausch bei Telekom Wellenlängen","_id":"173"}],"citation":{"ama":"Heinisch N, Köcher N, Bauch D, Schumacher S.

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>"}],"date_created":"2025-09-12T11:23:33Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"}],"status":"public","publisher":"American Physical Society (APS)","_id":"61257","user_id":"16199","volume":6,"citation":{"mla":"Wingenbach, Jan, et al. “Manipulating Spectral Topology and Exceptional Points by Nonlinearity in Non-Hermitian Polariton Systems.” <i>Physical Review Research</i>, vol. 6, no. 1, 013148, American Physical Society (APS), 2024, doi:<a href=\"https://doi.org/10.1103/physrevresearch.6.013148\">10.1103/physrevresearch.6.013148</a>.","ama":"Wingenbach J, Schumacher S, Ma X.

However, the capacity of n‐dopants to produce thermally stable n‐doped OSC films has not been thoroughly explored, with few reports of high thermal stability. Here, a novel n‐dopant, phosphazenium tetrafluoroborate (P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>) is introduced, which effectively induces n‐doping in N2200, P(PzDPP‐CT2) and several other commonly used OSCs. Remarkably, the electrical conductivity of P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>‐doped OSC films remains almost unchanged even after heating at temperatures &gt; 150 °C for 24 h, far superior to the films doped with benchmark N‐DMBI. The exceptional thermal stability observed in P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>‐doped P(PzDPP‐CT2) films allows for stable operation of the corresponding organic thermoelectric devices at 150 °C for 16 h, a milestone not previously achieved.

InP is also a leading material for photonic integrated circuits and computing, where ultrafast near‐surface behavior is key. A previous study described electronic pathways at the phosphorus‐rich (P‐rich) surface of p‐doped InP(100) using time‐resolved two‐photon photoemission (tr‐2PPE) spectroscopy. Here, the intricate electron pathways of the P‐rich InP surface modified with ALD‐deposited TiO<jats:sub>2</jats:sub> are explored. Photoexcited bulk InP electrons migrate through a bulk‐to‐surface transition cluster of states and surface states and inject into the TiO<jats:sub>2</jats:sub> conduction band (CB). Energy levels and occupation dynamics of CB states in P‐rich InP and TiO<jats:sub>2</jats:sub> adlayers are observed, with discrete states preserved up to 10 nm TiO<jats:sub>2</jats:sub> deposition. Thermalization lifetimes of excited electrons &gt; 0.8 eV above the InP conduction band minimum (CBM) are preserved for layer thicknesses up to 2.5 nm. Annealing at 300 °C to achieve crystalline TiO<jats:sub>2</jats:sub> reconstructions destroys interfacial states, affecting charge transfer. These observations enable innovative engineering of the P‐rich InP/TiO<jats:sub>2</jats:sub> heterointerface, opening new possibilities for studying hot‐carrier extraction, adsorbate effects, surface plasmons, and improving photovoltaic and PEC water‐splitting devices.</jats:p>","lang":"eng"}],"publication":"Advanced Functional Materials","issue":"49","doi":"10.1002/adfm.202409455","article_number":"2409455","language":[{"iso":"eng"}],"date_updated":"2025-12-05T13:35:09Z","publication_status":"published","intvolume":"        34","title":"Ultrafast Electron Dynamics at the P‐rich Indium Phosphide/TiO<sub>2</sub> Interface","year":"2024","author":[{"first_name":"Jonathan","last_name":"Diederich","full_name":"Diederich, Jonathan"},{"full_name":"Rojas, Jennifer Velazquez","last_name":"Rojas","first_name":"Jennifer Velazquez"},{"last_name":"Paszuk","first_name":"Agnieszka","full_name":"Paszuk, Agnieszka"},{"full_name":"Pour, Mohammad Amin Zare","last_name":"Pour","first_name":"Mohammad Amin Zare"},{"first_name":"Christian","last_name":"Höhn","full_name":"Höhn, Christian"},{"full_name":"Alvarado, Isaac Azahel Ruiz","first_name":"Isaac Azahel Ruiz","last_name":"Alvarado"},{"full_name":"Schwarzburg, Klaus","last_name":"Schwarzburg","first_name":"Klaus"},{"full_name":"Ostheimer, David","first_name":"David","last_name":"Ostheimer"},{"first_name":"Rainer","last_name":"Eichberger","full_name":"Eichberger, Rainer"},{"id":"468","full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero"},{"full_name":"Hannappel, Thomas","last_name":"Hannappel","first_name":"Thomas"},{"full_name":"van de Krol, Roel","first_name":"Roel","last_name":"van de Krol"},{"full_name":"Friedrich, Dennis","first_name":"Dennis","last_name":"Friedrich"}],"publication_identifier":{"issn":["1616-301X","1616-3028"]}}]
