Stark many-body localization on a superconducting quantum processor
Quantum emulators, owing to their large degree of tunability and control, allow the
observation of fine aspects of closed quantum many-body systems, as either the regime …

Subdiffusion and heat transport in a tilted two-dimensional Fermi-Hubbard system
Using quantum gas microscopy, we study the late-time effective hydrodynamics of an
isolated cold-atom Fermi-Hubbard system subject to an external linear potential (a “tilt”). The …

Glimmers of a quantum KAM theorem: insights from quantum quenches in one-dimensional Bose gases
Real-time dynamics in a quantum many-body system are inherently complicated and hence
difficult to predict. There are, however, a special set of systems where these dynamics are …
