Mpemba effects in open nonequilibrium quantum systems

A Nava, R Egger - Physical Review Letters, 2024 - APS
We generalize the classical thermal Mpemba effect (where an initially hot system relaxes
faster to the final equilibrium state than a cold one) to open quantum systems coupled to …

Out-of-equilibrium open quantum systems: A comparison of approximate quantum master equation approaches with exact results

A Purkayastha, A Dhar, M Kulkarni - Physical Review A, 2016 - APS
We present the Born-Markov approximated Redfield quantum master equation (RQME)
description for an open system of noninteracting particles (bosons or fermions) on an …

We investigate open quantum dynamics for a one-dimensional incommensurate Aubry–
André–Harper lattice chain, a part of which is initially filled with electrons and is further …

[PDF][PDF] A novel hybrid numerical renormalization group approach to non-equilibrium dynamics and spectral functions

JO Böker - 2021 - eldorado.tu-dortmund.de
Solid state physics is a materials science, that is intended to explain macroscopic behavior

Self-contained n-qubit quantum refrigerator

M Ghanavati, H Movahhedian - International Journal of Quantum …, 2014 - World Scientific
Brunner et al.[Phys. Rev. E 85 (2012) 05111] have claimed that," essentially only the
smallest machines can approach Carnot efficiency". We have verified this claim by raising …

[PDF][PDF] Nonequilibrium steady-state transport in quantum impurity models

F Schwarz - 2017 - edoc.ub.uni-muenchen.de
Quantum impurity models are of great interest in solid state physics as they describe
impurities in metals as well as nanostructures such as quantum dots. Furthermore, they are …
