Testing the validity of the 'local'and 'global'GKLS master equations on an exactly solvable model

JO González, LA Correa, G Nocerino… - Open Systems & …, 2017 - World Scientific
When deriving a master equation for a multipartite weakly-interacting open quantum
systems, dissipation is often addressed locally on each component, ie ignoring the coherent …

Fast and slow thermal processes in harmonic scalar lattices

VA Kuzkin, AM Krivtsov - Journal of Physics: Condensed Matter, 2017 - iopscience.iop.org
An approach for analytical description of thermal processes in harmonic lattices is
presented. We cover longitudinal and transverse vibrations of chains and out-of-plane …

Stochastic simulation of dissipative quantum oscillators

CR Hogg, J Glatthard, F Cerisola, J Anders - arXiv preprint arXiv …, 2024 - arxiv.org
Generic open quantum systems are notoriously difficult to simulate unless one looks at
specific regimes. In contrast, classical dissipative systems can often be effectively described …

Fundamental limits for cooling of linear quantum refrigerators

N Freitas, JP Paz - Physical Review E, 2017 - APS
We study the asymptotic dynamics of arbitrary linear quantum open systems that are
periodically driven while coupled with generic bosonic reservoirs. We obtain exact results for …

From nonequilibrium Green's functions to quantum master equations for the density matrix and out-of-time-order correlators: Steady-state and adiabatic dynamics

B Bhandari, R Fazio, F Taddei, L Arrachea - Physical Review B, 2021 - APS
We consider a finite quantum system under slow driving and weakly coupled to thermal
reservoirs at different temperatures. We present a systematic derivation of the quantum …

Nonequilibrium steady states of long-range coupled harmonic chains

F Andreucci, S Lepri, S Ruffo, A Trombettoni - Physical Review E, 2023 - APS
We perform a numerical study of transport properties of a one-dimensional chain with
couplings decaying as an inverse power r−(1+ σ) of the intersite distance r and open …

Thermal transport in out-of-equilibrium quantum harmonic chains

F Nicacio, A Ferraro, A Imparato, M Paternostro… - Physical Review E, 2015 - APS
We address the problem of heat transport in a chain of coupled quantum harmonic
oscillators, exposed to the influences of local environments of various nature, stressing the …

Potential renormalisation, Lamb shift and mean-force Gibbs state--to shift or not to shift?

LA Correa, J Glatthard - arXiv preprint arXiv:2305.08941, 2023 - arxiv.org
Often, the microscopic interaction mechanism of an open quantum system gives rise to
acounter term'which renormalises the system Hamiltonian. Such term compensates for the …

[HTML][HTML] Pushing the limits of the reaction-coordinate mapping

LA Correa, B Xu, B Morris, G Adesso - The Journal of chemical physics, 2019 - pubs.aip.org
The reaction-coordinate mapping is a useful technique to study complex quantum
dissipative dynamics into structured environments. In essence, it aims to mimic the original …

A quantum Otto engine with finite heat baths: Energy, correlations, and degradation

A Pozas-Kerstjens, EG Brown… - New Journal of …, 2018 - iopscience.iop.org
We study a driven harmonic oscillator operating an Otto cycle by strongly interacting with two
thermal baths of finite size. Using the tools of Gaussian quantum mechanics, we directly …
