Weak-link to tunneling crossover in an atomic Josephson junction
Vijay Pal Singh, Erik Bernhart, Marvin Röhrle +3
We present a unified, quantitative description of transport across the crossover between hydrodynamic weak-link flow and tunneling-dominated Josephson dynamics in a three-dimension…
Phase-resolved multichannel quantum escape between limit cycles
Caroline Nowoczyn, Ludwig Mathey, Kilian Seibold
Driven-dissipative quantum systems can recover stable dynamical attractors in the semiclassical limit, including coexisting limit cycles. At finite fluctuation strength, this class…
Universal quantum melting of quasiperiodic attractors in driven-dissipative cavities
Caroline Nowoczyn, Ludwig Mathey, Kilian Seibold
Nonlinear classical mechanics has established rich phenomena. These include limit tori defined by toroidal attractors supporting quasiperiodic motion with incommensurate frequencie…
Deterministic Quantum Jump (DQJ) Method for Weakly Dissipative Systems
Marcus Meschede, Ludwig Mathey
Physical quantum systems are generically coupled to an environment, resulting in open system dynamics. A typical approach to simulating this dynamics is to propagate the density ma…
First-order transition into a topological superfluid state in an atom-cavity system
Hannah Kleine-Pollmann, Ludwig Mathey
We propose to combine Bose-Einstein condensation in higher Bloch bands and a driven-dissipative cavity-BEC system into a hybrid light-matter platform. Specifically, the condensate…
Quantum Deep Learning: A Comprehensive Review
Yanjun Ji, Zhao-Yun Chen, Marco Roth +10
Quantum deep learning (QDL) explores the use of both quantum and quantum-inspired resources to determine when deep learning's core capabilities, such as expressivity, generalizatio…
