Quantum work and the thermodynamic cost of quantum measurements
(American Physical Society, 2016-07)
Quantum work is usually determined from two projective measurements of the energy at the beginning and at the end of a thermodynamic process. However, this paradigm cannot be considered thermodynamically consistent as it ...
Thermodynamics and Steady State of Quantum Motors and Pumps Far from Equilibrium
(MDPI, 2019-08-23)
In this article, we briefly review the dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. We then extend previous results to provide new theoretical tools for a systematic study ...
Quantum thermodynamics aspects with a thermal reservoir based on PT -symmetric Hamiltonians
(2021-08-01)
We present results concerning aspects of quantum thermodynamics under the background of non-Hermitian quantum mechanics for the dynamics of a quantum harmonic oscillator. Since a better control over the parameters in quantum ...
Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Dynamics and Thermodynamics of Linear Quantum Open Systems
(Amer Physical Soc, 2013-04-29)
We analyze the evolution of the quantum state of networks of quantum oscillators coupled with arbitrary external environments. We show that the reduced density matrix of the network always obeys a local master equation ...
Reconciliation of quantum local master equations with thermodynamics
(IOP Publishing, 2018-11)
The study of open quantum systems often relies on approximate master equations derived under the assumptions of weak coupling to the environment. However when the system is made of several interacting subsystems such a ...
Quantum batteries at the verge of a phase transition
(IOP, 2022)
Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quantum device that is in thermal equilibrium, ...
Fundamental limits for cooling of linear quantum refrigerators
(American Physical Society, 2017-01)
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 the heat flowing from each reservoir, and ...
