The intensive computation and bandwidth demand for ERI evaluation presents a significant challenge for quantum-mechanics-based atomistic simulations with hybrid density functional theory: due to the tens of trillions of ERI computations in each time step, practical applications are usually limited to thousands of atoms. In this work, we propose SERI, a high-throughput streaming accelerator for ERI computation on HBM-based FPGAs. In contrast to prior buffer-based designs, SERI proposes a novel streaming architecture to address the on-chip buffer limitation and the floorplanning challenge, and leverages the high-bandwidth memory to overcome the bandwidth bottleneck in prior designs. Moreover, to meet the varying computation, bandwidth, and floorplanning requirements between the 55 canonical quartet classes in ERI calculation, we design an automation tool, together with an accurate performance model, to automatically customize the architecture and floorplanning strategy for each canonical quartet class to maximize their throughput. Our performance evaluation on the AMD/Xilinx Alveo U280 FPGA board shows that, SERI achieves an average speedup of 9.80 x over the previous best-performing FPGA design, a 3.21x speedup over a 64-core AMD EPYC 7713 CPU, and a 15.64x speedup over an Nvidia A40 GPU. It reaches a peak throughput of 23.8 GERIS ($10^9$ ERIs per second) on one Alveo U280 FPGA.

Despite its fundamental importance, precisely defining atomic and molecular surfaces has long been a puzzle. Among the available definitions, a straightforward and elegant approach by Bader describes a molecular surface as an iso-density surface beyond which the electron density drops below a certain cut-off. However, so far neither this theory nor a decisive value for the density cut-off have been amenable to experimental verification due to the limitations of conventional experimental methods. In the present study, we employ a state-of-the-art experimental method based on the recently developed concept of thermodynamically effective (TE) surfaces to tackle this longstanding problem. By studying a set of 104 molecules, a close to perfect agreement between quantum chemical evaluations of iso-density surfaces contoured at a cut-off density of 0.0016 a.u. and experimental results obtained via thermodynamic phase change data is demonstrated, with a mean unsigned percentage deviation of 1.6% and a correlation coefficient of 0.995. Accordingly, we suggest the iso-density surface contoured at an electron density value of 0.0016 a.u. as a representation of the surface of atoms and molecules."}],"issue":"1","publication":"Nature Communications","type":"journal_article","date_created":"2024-10-18T07:00:00Z"},{"language":[{"iso":"eng"}],"doi":"10.1021/acs.jpca.4c04529","year":"2024","title":"On the Theoretical Quantification of Radii of Atoms in Molecules","author":[{"full_name":"Alibakhshi, Amin","first_name":"Amin","last_name":"Alibakhshi"},{"last_name":"Schäfer","first_name":"Lars V.","full_name":"Schäfer, Lars V."}],"publication_identifier":{"issn":["1089-5639","1520-5215"]},"publication_status":"published","date_updated":"2024-10-18T07:01:06Z","intvolume":" 128","date_created":"2024-10-18T07:00:54Z","type":"journal_article","publication":"The Journal of Physical Chemistry A","issue":"32","page":"6819-6823","_id":"56679","publisher":"American Chemical Society (ACS)","user_id":"67287","volume":128,"status":"public","citation":{"bibtex":"@article{Alibakhshi_Schäfer_2024, title={On the Theoretical Quantification of Radii of Atoms in Molecules}, volume={128}, DOI={10.1021/acs.jpca.4c04529}, number={32}, journal={The Journal of Physical Chemistry A}, publisher={American Chemical Society (ACS)}, author={Alibakhshi, Amin and Schäfer, Lars V.}, year={2024}, pages={6819–6823} }","ama":"Alibakhshi A, Schäfer LV.

Traditionally, joints are cylindrical and rotationally symmetric. In the present study, non-rotationally symmetric joints are used for joining steel and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also analyzes the impact of non-rotational symmetric joint rotation on the load-bearing capacity. Single lap joint specimens were fabricated using the In-Mold assembly technique for joining steel sheets with GMT. Tensile shear tests were performed on different orientations of the joint geometry, and it was observed that changing the joint orientation influences the load-bearing capacity. The joints are constitutively modeled using beam elements and the influence of joint rotation on load distribution is examined through a static simulation study.

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.","lang":"eng"}],"publication":"APL Quantum","issue":"3","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"},{"_id":"623"}],"type":"journal_article","date_created":"2025-09-12T11:08:59Z"},{"citation":{"mla":"Heinisch, Nils, et al. “Swing-up Dynamics in Quantum Emitter Cavity Systems: Near Ideal Single Photons and Entangled Photon Pairs.” Physical Review Research, vol. 6, no. 1, L012017, American Physical Society (APS), 2024, doi:10.1103/physrevresearch.6.l012017.","ama":"Heinisch N, Köcher N, Bauch D, 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.\r\n \r\n \r\n \r\n \r\n Published by the American Physical Society\r\n 2024\r\n \r\n \r\n "}],"date_created":"2025-09-12T11:16:31Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"type":"journal_article","publication_identifier":{"issn":["2643-1564"]},"author":[{"orcid":"0009-0006-0984-2097","last_name":"Heinisch","first_name":"Nils","full_name":"Heinisch, Nils","id":"90283"},{"id":"79191","full_name":"Köcher, Nikolas","first_name":"Nikolas","last_name":"Köcher"},{"full_name":"Bauch, David","last_name":"Bauch","first_name":"David"},{"id":"27271","orcid":"0000-0003-4042-4951","first_name":"Stefan","last_name":"Schumacher","full_name":"Schumacher, Stefan"}],"title":"Swing-up dynamics in quantum emitter cavity systems: Near ideal single photons and entangled photon pairs","year":"2024","intvolume":" 6","publication_status":"published","date_updated":"2025-09-12T11:18:05Z","language":[{"iso":"eng"}],"article_number":"L012017","doi":"10.1103/physrevresearch.6.l012017"},{"_id":"61255","publisher":"Walter de Gruyter GmbH","page":"509-518","volume":13,"user_id":"16199","status":"public","citation":{"ieee":"T.

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.

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.\r\n \r\n \r\n \r\n \r\n Published by the American Physical Society\r\n 2024\r\n \r\n \r\n ","lang":"eng"}],"article_number":"013148","language":[{"iso":"eng"}],"doi":"10.1103/physrevresearch.6.013148","year":"2024","title":"Manipulating spectral topology and exceptional points by nonlinearity in non-Hermitian polariton systems","author":[{"id":"69187","last_name":"Wingenbach","first_name":"Jan","full_name":"Wingenbach, Jan"},{"first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan","id":"27271"},{"id":"59416","full_name":"Ma, Xuekai","last_name":"Ma","first_name":"Xuekai"}],"publication_identifier":{"issn":["2643-1564"]},"publication_status":"published","date_updated":"2025-09-12T11:24:59Z","intvolume":" 6","citation":{"ama":"Wingenbach J, Schumacher S, Ma X.

However, the utilization of their network capabilities is often challenging and error-prone because the whole network stack and communication patterns have to be implemented and managed on the FPGAs. Also, this approach conceptually involves a trade-off between the performance potential of improved communication and the impact of resource consumption for communication infrastructure, since the utilized resources on the FPGAs could otherwise be used for computations. In this work, we investigate this trade-off, firstly, by using synthetic benchmarks to evaluate the different configuration options of the communication framework ACCL and their impact on communication latency and throughput. Finally, we use our findings to implement a shallow water simulation whose scalability heavily depends on low-latency communication. With a suitable configuration of ACCL, good scaling behavior can be shown to all 48 FPGAs installed in the system. Overall, the results show that the availability of inter-FPGA communication frameworks as well as the configurability of framework and network stack are crucial to achieve the best application performance with low latency communication.","lang":"eng"}],"publication":"Lecture Notes in Computer Science"},{"status":"public","publisher":"Association for Computing Machinery (ACM)","_id":"56604","page":"1-28","volume":17,"user_id":"3145","citation":{"ieee":"L.
