Quantum response of dephasing open systems [PDF]

, 2011
We develop a theory of adiabatic response for open systems governed by Lindblad evolutions. The theory determines the dependence of the response coefficients on the dephasing rates and allows for residual dissipation even when the ground state is ...

Simulating Quantum Dissipation in Many-Body Systems

, 2001
An efficient Path Integral Monte Carlo procedure is proposed to simulate the behavior of quantum many-body dissipative systems described within the framework of the influence functional.

Fundamental Aspects of Quantum Brownian Motion [PDF]

, 2004
With this work we elaborate on the physics of quantum noise in thermal equilibrium and in stationary non-equilibrium. Starting out from the celebrated quantum fluctuation-dissipation theorem we discuss some important consequences that must hold for open,

Emission characteristics of laser-driven dissipative coupled-cavity systems

, 2011
We consider a laser-driven and dissipative system of two coupled cavities with Jaynes-Cummings nonlinearity. In particular, we investigate both incoherent and coherent laser driving, corresponding to different experimental situations.

Out-of-equilibrium evolution of kinetically constrained many-body quantum systems under purely dissipative dynamics

, 2014
We explore the relaxation dynamics of quantum many-body systems that undergo purely dissipative dynamics through non-classical jump operators that can establish quantum coherence.

The Observables of a Dissipative Quantum System [PDF]

Open Systems & Information Dynamics, 2012
A time-dependent product is introduced between the observables of a dissipative quantum system, that accounts for the effects of dissipation on observables and commutators. In the t → ∞ limit this yields a contracted algebra. This product can be transported back by duality on the space of states.

Many-body open quantum systems

SciPost Physics Lecture Notes
These lecture notes discuss the recent theoretical advances in the understanding of open quantum many-body physics in platforms where both dissipative and coherent processes can be tuned and controlled to a high degree.

Entropy and Its Quantum Thermodynamical Implication for Anomalous Spectral Systems

, 2011
The state function entropy and its quantum thermodynamical implication for two typical dissipative systems with anomalous spectral densities are studied by investigating on their low-temperature quantum behavior. In all cases it is found that the entropy

Chaos and high temperature pure state thermalization

Journal of High Energy Physics, 2019
Classical arguments for thermalization of isolated systems do not apply in a straightforward way to the quantum case. Recently, there has been interest in diagnostics of quantum chaos in many-body systems.
