The usual paradigm of open quantum systems falls short when the environment is actually coupled to additional fields or components that drive it out of equilibrium. Here we explore the simplest such scenario, by considering a two level system coupled to a first thermal reservoir that in turn couples to a second thermal bath at a different temperature. We derive a master equation description for the system and show that, in this situation, the dynamics can be especially rich. In particular, we… 

Relaxation and Prethermalization in an Isolated Quantum System

Measurements of full quantum mechanical probability distributions of matter-wave interference are used to study the relaxation dynamics of a coherently split one-dimensional Bose gas and obtained comprehensive information about the dynamical states of the system.

Prethermalization and Thermalization in Isolated Quantum Systems

Prethermalization has been extensively studied in systems close to integrability. We propose a more general, yet conceptually simpler, setup for this phenomenon. We consider a --possibly

Generalized Gibbs ensemble prediction of prethermalization plateaus and their relation to nonthermal steady states in integrable systems

A quantum many-body system which is prepared in the ground state of an integrable Hamiltonian does not directly thermalize after a sudden small parameter quench away from integrability. Rather, it

Thermalization and prethermalization in isolated quantum systems: a theoretical overview

The approach to thermal equilibrium, or thermalization, in isolated quantum systems is among the most fundamental problems in statistical physics. Recent theoretical studies have revealed that

Weak-coupling master equation for arbitrary initial conditions

The structure of the initial system-environment state is fundamental to determining the nature and characteristics of the evolution of such an open quantum system. The usual assumption is to consider

Perturbative approach to weakly driven many-particle systems in the presence of approximate conservation laws

We develop a Liouville perturbation theory for weakly driven and weakly open quantum systems in situations when the unperturbed system has a number of conservations laws. If the perturbation violates

Dynamics of the dissipative two-state system

This paper presents the results of a functional-integral approach to the dynamics of a two-state system coupled to a dissipative environment. It is primarily an extended account of results obtained

Time-dependent generalized Gibbs ensembles in open quantum systems

Generalized Gibbs ensembles have been used as powerful tools to describe the steady state of integrable many-particle quantum systems after a sudden change of the Hamiltonian. Here we demonstrate

Prethermalization and Thermalization in Models with Weak Integrability Breaking.

This work focuses on a class of spinless fermion models with weak interactions and employs equation of motion techniques that can be viewed as generalizations of quantum Boltzmann equations, finding the method to be very accurate as long as interactions are weak.

Stochastic surrogate Hamiltonian.

The surrogate Hamiltonian is a general scheme to simulate the many body quantum dynamics composed of a primary system coupled to a bath that can simulate quantum dynamics of the primary system from short times to thermal equilibrium.
