Quantum thermodynamically consistent local master equations

open access: yesPhysical Review Research, 2021
Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body systems. These equations, however, are believed to lead to thermodynamic anomalies and violation of the laws of thermodynamics. In contrast,

Entropy Exchange and Thermodynamic Properties of the Single Ion Cooling Process

open access: yesEntropy, 2019
A complete quantum cooling cycle may be a useful platform for studying quantum thermodynamics just as the quantum heat engine does. Entropy change is an important feature which can help us to investigate the thermodynamic properties of the single ion ...

Gravitational Thermodynamics of Space-time Foam in One-loop Approximation [PDF]

open access: yes, 1999
We show from one-loop quantum gravity and statistical thermodynamics that the thermodynamics of quantum foam in flat space-time and Schwarzschild space-time is exactly the same as that of Hawking-Unruh radiation in thermal equilibrium. This means we show

Daemonic ergotropy: enhanced work extraction from quantum correlations

open access: yesnpj Quantum Information, 2017
Quantum thermodynamics: Quantum correlations are key for work extraction! A strong connection exists between the ability of a quantum system to perform thermodynamic work and the amount of quantum correlations that are set in its physical configuration ...

Quantum Thermodynamics: A Nonequilibrium Green's Functions Approach [PDF]

open access: yes, 2015
We establish the foundations of a nonequilibrium theory of quantum thermodynamics for noninteracting open quantum systems strongly coupled to their reservoirs within the framework of the nonequilibrium Green functions (NEGF). The energy of the system and

Entropy production along nonequilibrium quantum jump trajectories

open access: yesNew Journal of Physics, 2013
For classical nonequilibrium systems, the separation of the total entropy production into the adiabatic and nonadiabatic contributions is useful for understanding irreversibility in nonequilibrium thermodynamics.

A Resource Theory for Work and Heat [PDF]

open access: yes, 2017
Several recent results on thermodynamics have been obtained using the tools of quantum information theory and resource theories. So far, the resource theories utilised to describe thermodynamics have assumed the existence of an infinite thermal reservoir,

Introduction to Quantum Thermodynamics: History and Prospects

open access: yes, 2018
Quantum Thermodynamics is a continuous dialogue between two independent theories: Thermodynamics and Quantum Mechanics. Whenever the two theories addressed the same phenomena new insight has emerged.

Thermodynamics of Schwarzschild-(Anti-)de Sitter Black Holes with account of quantum corrections [PDF]

open access: yes, 1999
We discuss the quantum corrections to thermodynamics (and geometry) of S(A)dS BHs using large $N$ one-loop anomaly induced effective action for dilaton coupled matter (scalars and spinors).

Fluctuating Work: From Quantum Thermodynamical Identities to a Second Law Equality

open access: yesPhysical Review X, 2016
We investigate the connection between recent results in quantum thermodynamics and fluctuation relations by adopting a fully quantum mechanical description of thermodynamics.
