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 …

Stochastic simulation of dissipative quantum oscillators
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
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
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
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 …

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 …

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 …
