Quench, thermalization, and residual entropy across a non-Fermi liquid to Fermi liquid transition

Year: 2020

Type: article

Abstract: This work shows how a Fermi liquid evolves to a non-Fermi liquid and vice versa after a quantum quench in a model with a quantum critical point separating the two states. The quench is achieved by joining a fermion cluster having Sachdev-Ye-Kitaev-type interactions and a cluster of non-interacting fermions having Fermi liquid behavior. The critical point is approached when the sizes of the two clusters become equal.
