Adiabatic dynamics in open quantum critical many-body systems
arXiv:0805.0586 · doi:10.1103/PhysRevLett.101.175701
Abstract
The purpose of this work is to understand the effect of an external environment on the adiabatic dynamics of a quantum critical system. By means of scaling arguments we derive a general expression for the density of excitations produced in the quench as a function of its velocity and of the temperature of the bath. We corroborate the scaling analysis by explicitly solving the case of a one-dimensional quantum Ising model coupled to an Ohmic bath.
