Caustics in quantum many-body dynamics

W Kirkby, Y Yee, K Shi, DHJ O'Dell - Physical Review Research, 2022 - APS
We describe a new class of nonequilibrium quantum many-body phenomena in the form of
networks of caustics that dominate the many-body wave function in the semiclassical regime …

Optimized observable readout from single-shot images of ultracold atoms via machine learning

AUJ Lode, R Lin, M Büttner, L Papariello, C Lévêque… - Physical Review A, 2021 - APS
Single-shot images are the standard readout of experiments with ultracold atoms, the
imperfect reflection of their many-body physics. The efficient extraction of observables from …

Quantum-classical correspondence in a triple-well bosonic model: From integrability to chaos
