Nonequilibrium boundary-driven quantum systems: Models, methods, and properties

GT Landi, D Poletti, G Schaller - Reviews of Modern Physics, 2022 - APS
Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Dynamical maps beyond Markovian regime

D Chruściński - Physics Reports, 2022 - Elsevier
Quantum dynamical maps provide suitable mathematical representation of quantum
evolutions. When representing quantum states by density operators, the evident …

Open quantum system dynamics and the mean force Gibbs state

AS Trushechkin, M Merkli, JD Cresser… - AVS Quantum Science, 2022 - pubs.aip.org
The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a
standard assumption across all of the physical sciences. The Gibbs state is determined just …

Fundamental limitations in Lindblad descriptions of systems weakly coupled to baths

D Tupkary, A Dhar, M Kulkarni, A Purkayastha - Physical Review A, 2022 - APS
It is very common in the literature to write a Markovian quantum master equation in Lindblad
form to describe a system with multiple degrees of freedom and weakly connected to …

Weak and ultrastrong coupling limits of the quantum mean force Gibbs state

JD Cresser, J Anders - Physical Review Letters, 2021 - APS
The Gibbs state is widely taken to be the equilibrium state of a system in contact with an
environment at temperature T. However, non-negligible interactions between system and …

Nonequilibrium Green's function method for quantum thermal transport

JS Wang, BK Agarwalla, H Li, J Thingna - Frontiers of Physics, 2014 - Springer
This review deals with the nonequilibrium Green's function (NEGF) method applied to the
problems of energy transport due to atomic vibrations (phonons), primarily for small junction …

Canonically consistent quantum master equation

T Becker, A Schnell, J Thingna - Physical Review Letters, 2022 - APS
We put forth a new class of quantum master equations that correctly reproduce the
asymptotic state of an open quantum system beyond the infinitesimally weak system-bath …

Coherences and the thermodynamic uncertainty relation: Insights from quantum absorption refrigerators

J Liu, D Segal - Physical Review E, 2021 - APS
The thermodynamic uncertainty relation, originally derived for classical Markov-jump
processes, provides a tradeoff relation between precision and dissipation, deepening our …

Monitoring quantum Otto engines

J Son, P Talkner, J Thingna - PRX Quantum, 2021 - APS
Unlike classical systems, a measurement performed on a quantum system always alters its
state. In this work, the impacts of two diagnostic schemes to determine the performance of …

Lindbladian approximation beyond ultraweak coupling

T Becker, LN Wu, A Eckardt - Physical Review E, 2021 - APS
Away from equilibrium, the properties of open quantum systems depend on the details of
their environment. A microscopic derivation of a master equation (ME) is therefore crucial. Of …
