Can Quantum Correlations Lead to Violation of the Second Law of Thermodynamics?

open access: yesEntropy, 2021
Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states,

Quantum thermodynamics of a quantum sized AdS black hole

open access: yesNuclear Physics B, 2022
In this paper, we investigate the effects of non-perturbative quantum gravitational corrections on a quantum sized AdS black hole. It will be observed that these non-perturbative quantum gravitational corrections modify the stability of this black hole ...

Correlations as a resource in quantum thermodynamics. [PDF]

open access: yesNat Commun, 2019
AbstractThe presence of correlations in physical systems can be a valuable resource for many quantum information tasks. They are also relevant in thermodynamic transformations, and their creation is usually associated to some energetic cost. In this work, we study the role of correlations in the thermodynamic process of state formation in the single ...

Quantum thermodynamics of general quantum processes [PDF]

open access: yesPhysical Review E, 2015
Accurately describing work extraction from a quantum system is a central objective for the extension of thermodynamics to individual quantum systems. The concepts of work and heat are surprisingly subtle when generalizations are made to arbitrary quantum states.

Thermodynamic Principle for Quantum Metrology

open access: yesPhysical Review Letters, 2022
The heat dissipation in quantum metrology represents not only an unavoidable problem towards practical applications of quantum sensing devices but also a fundamental relationship between thermodynamics and quantum metrology. However, a general thermodynamic principle which governs the rule of energy consumption in quantum metrology, similar to Landauer'
