Nonequilibrium thermodynamics of quantum coherence beyond linear response
Communications PhysicsQuantum thermodynamics allows for the interconversion of quantum coherence and mechanical work. Quantum coherence is thus a potential physical resource for quantum machines.

No Entropy Production in Quantum Thermodynamics [PDF]
arXiv, 2020 In this work we will show that there exists a fundamental difference between microscopic quantum thermodynamics and macroscopic classical thermodynamics. It will be proved that the entropy production in quantum thermodynamics always vanishes for both closed and open quantum thermodynamic systems.

Repeated interactions and quantum stochastic thermodynamics at strong coupling [PDF]
Phys. Rev. Lett. 123, 180604 (2019), 2019 The thermodynamic framework of repeated interactions is generalized to an arbitrary open quantum system in contact with a heat bath. Based on these findings the theory is then extended to arbitrary measurements performed on the system. This constitutes a direct experimentally testable framework in strong coupling quantum thermodynamics. By construction,

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 ...

Integration of Quantum, Statistical, and Irreversible Thermodynamics in A Coherent Framework [PDF]
arXiv, 2023 The combined law of thermodynamics derived by Gibbs laid the foundation of thermodynamics though only applicable to systems without internal processes. Gibbs further derived the classical statistical thermodynamics in terms of the probability of configurations in a system, which was extended to quantum mechanics-based statistical thermodynamics by ...

New Journal of PhysicsWe compare how the impossibility of a universal work extractor from coherence arises from different approaches to quantum thermodynamics: an explicit protocol accounting for all relevant quantum resources, and axiomatic, information-theoretic constraints

Some Trends in Quantum Thermodynamics
Entropy, 2014 Traditional answers to what the 2nd Law is are well known. Some are based on the microstate of a system wandering rapidly through all accessible phase space, while others are based on the idea of a system occupying an initial multitude of states due to ...

Thermodynamic and Quantum Thermodynamic Analyses of Brownian Movement [PDF]
arXiv, 2006 Thermodynamic and quantum thermodynamic analyses of Brownian movement of a solvent and a colloid passing through neutral thermodynamic equilibrium states only. It is shown that Brownian motors and E. coli do not represent Brownian movement.

Work extraction and thermodynamics for individual quantum systems
, 2014 Thermodynamics is traditionally concerned with systems comprised of a large number of particles. Here we present a framework for extending thermodynamics to individual quantum systems, including explicitly a thermal bath and work-storage device ...

Quantum supremacy of many-particle thermal machines
New Journal of Physics, 2016 While the emergent field of quantum thermodynamics has the potential to impact energy science, the performance of thermal machines is often classical.
