Quasiprobabilities in Quantum Thermodynamics and Many-Body Systems [PDF]
PRX QuantumIn this tutorial, we present the definition, interpretation, and properties of some of the main quasiprobabilities that can describe the statistics of measurement outcomes evaluated at two or more times. Such statistics incorporate the incompatibility of

Nonequilibrium thermodynamics in cavity optomechanics
Fundamental Research, 2023 Classical thermodynamics has been a great achievement in dealing with systems that are in equilibrium or near equilibrium. As an emerging field, nonequilibrium thermodynamics provides a general framework for understanding the nonequilibrium processes ...

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

Towards Nonlinear Quantum Thermodynamics [PDF]
The European Physical Journal Special TopicsWe have recently put forth several schemes of unconventional, nonlinearly-enabled thermodynamic (TD) devices that can operate in either the classical or the quantum domain by transforming thermal-state input in multiple uncorrelated modes into non-gaussian state output in selected modes: a four-mode Kerr-nonlinear interferometer that acts as a heat ...

Quantum Thermodynamics with Degenerate Eigenstate Coherences
Entropy, 2016 We establish quantum thermodynamics for open quantum systems weakly coupled to their reservoirs when the system exhibits degeneracies. The first and second law of thermodynamics are derived, as well as a finite-time fluctuation theorem for mechanical ...

Reinforcement Learning Approach to Nonequilibrium Quantum Thermodynamics. [PDF]
Physical Review Letters, 2020 We use a reinforcement learning approach to reduce entropy production in a closed quantum system brought out of equilibrium. Our strategy makes use of an external control Hamiltonian and a policy gradient technique.

Quantum thermodynamically consistent local master equations
Physical 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
Entropy, 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 ...

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

Daemonic ergotropy: enhanced work extraction from quantum correlations
npj 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 ...
