Dynamics of a quantum phase transition and relaxation to a steady state
J Dziarmaga - Advances in Physics, 2010 - Taylor & Francis
We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

Quantum quench dynamics of the Luttinger model
The dynamics of the Luttinger model after a quantum quench is studied. We compute in
detail one-and two-point correlation functions for two types of quenches: from a …

Exotic freezing of response in a quantum many-body system
A Das - Physical Review B—Condensed Matter and Materials …, 2010 - APS
We show that when a quantum many-body system is subjected to coherent periodic driving,
the response may exhibit exotic freezing behavior in high driving frequency (ω) regime. In a …

Quantum quench from a thermal initial state
We consider a quantum quench in a system of free bosons, starting from a thermal initial
state. As in the case where the system is initially in the ground state, any finite subsystem …

Space and time renormalization in phase transition dynamics
When a system is driven across a quantum critical point at a constant rate, its evolution must
become nonadiabatic as the relaxation time τ diverges at the critical point. According to the …
