报告摘要

Ultracold fermionic atoms allow the study of strongly interacting matter, relevant for many different fields of physics, such as strongly interacting electrons in metals, neutron matter in the crust of neutron stars, and the quark-gluon plasma of the early universe. Especially, understanding the nonequilibrium dynamics of such complex quantum systems is more challenging in the presence of strong correlations between particles.  In this talk, I will present our recent study on the dynamics of a scale invariant trapped unitary Fermi gas, including novel expansion and finite-time quantum thermodynamics.  The far-from-equilibrium dynamics of quantum devices can be tailored by using the symmetry to suppress quantum friction. The ability to implement such manipulation in a unitary Fermi gas offers new avenues in quantum control for strongly-coupled many-body systems. It can be harnessed for the experimental test of predicted quantum anomalies in quantum gases confined to two-dimensions and quantum supremacy of many-particle thermal machines.
