Markovian master equations for quantum thermal machines: local versus global approach

PP Hofer, M Perarnau-Llobet, LDM Miranda… - New Journal of …, 2017‏ - iopscience.iop.org
The study of quantum thermal machines, and more generally of open quantum systems,
often relies on master equations. Two approaches are mainly followed. On the one hand …

Coherence-enhanced constancy of a quantum thermoelectric generator

K Ptaszyński - Physical Review B, 2018‏ - APS
The study shows that presence of the quantum coherent, unitary component of the evolution
of the system can improve constancy of heat engines, ie, decrease fluctuations of the output …

Spin quantum heat engines with shortcuts to adiabaticity

B Çakmak, ÖE Müstecaplıoğlu - Physical Review E, 2019‏ - APS
We consider a finite-time quantum Otto cycle with single-and two spin-1/2 systems as its
working medium. To mimic adiabatic dynamics at a finite time, we employ a shortcut-to …

[HTML][HTML] Nonequilibrium thermodynamics in cavity optomechanics

J Sheng, C Yang, H Wu - Fundamental Research, 2023‏ - Elsevier

equilibrium or near equilibrium. As an emerging field, nonequilibrium thermodynamics …

Autonomous quantum heat engine based on non-Markovian dynamics of an optomechanical Hamiltonian

M Rasola, M Möttönen - Scientific Reports, 2024‏ - nature.com
We propose a recipe for demonstrating an autonomous quantum heat engine where the
working fluid consists of a harmonic oscillator, the frequency of which is tuned by a driving …

Certifying quantum signatures in thermodynamics and metrology via contextuality of quantum linear response

M Lostaglio - Physical Review Letters, 2020‏ - APS
I identify a fundamental difference between classical and quantum dynamics in the linear
response regime by showing that the latter is, in general, contextual. This allows me to …

Non-Markovian thermal operations boosting the performance of quantum heat engines

K Ptaszyński - Physical Review E, 2022‏ - APS
It is investigated whether non-Markovianity, ie, the memory effects resulting from the
coupling of the system to its environment, can be beneficial for the performance of quantum …
