Talk

We present a framework for local quantum cooling that can be efficiently applied to large-scale Fermi systems. The method introduces local Hermitian operators as a cooling potential while strictly preserving the unitarity of time evolution. Our formulation scales favorably with system size and can be seamlessly integrated into time-dependent density functional theory frameworks. We demonstrate...

Josephson junctions provide a fundamental platform to study the interplay between macroscopic phase coherence and dissipation, with relevance ranging from quantum technologies and superconductors to neutron stars. Ultracold atomic gases, with tunable interactions and controllable geometries, enable exploration of Josephson dynamics across the BEC–BCS crossover within a single system.

We...
