Quantum thermodynamics of general quantum processes [PDF]
Physical 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.

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

Work, heat and entropy production along quantum trajectories
, 2018 Quantum open systems evolve according to completely positive, trace preserving maps acting on the density operator, which can equivalently be unraveled in term of so-called quantum trajectories. These stochastic sequences of pure states correspond to the

Thermodynamics as a Consequence of Information Conservation [PDF]
Quantum, 2019 Thermodynamics and information have intricate interrelations. Often thermodynamics is considered to be the logical premise to justify that $\textit{information is physical}$ - through Landauer's principle -, thereby also linking information and ...

Second Law-Like Inequalities with Quantum Relative Entropy: An Introduction [PDF]
, 2012 We review the fundamental properties of the quantum relative entropy for finite-dimensional Hilbert spaces. In particular, we focus on several inequalities that are related to the second law of thermodynamics, where the positivity and the monotonicity of

Quantum corrections to the thermodynamics of black branes
Journal of High Energy Physics, 2021 In this paper we study the thermodynamics of black branes at quantum scales. We analyze both perturbative and non-perturbative corrections to the thermodynamics of such black branes.

Relativistic quantum thermodynamics of moving systems [PDF]
, 2020 We analyse the thermodynamics of a quantum system in a trajectory of constant velocity that interacts with a static thermal bath. The latter is modeled by a massless scalar field in a thermal state.

Nonequilibrium thermodynamics of quantum friction [PDF]
Physical Review A, 2020 Thermodynamic principles are often deceptively simple and yet surprisingly powerful. We show how a simple rule, such as the net flow of energy in and out of a moving atom under nonequilibrium steady state condition, can expose the shortcomings of many popular theories of quantum friction.

Advanced Engineering Materials, EarlyView.This article provides an overview of recent advancements in bulk processing of rare‐earth‐free hard magnetic materials. It also addresses related simulation approaches at different scales. The research on rare‐earth‐free magnetic materials has increased significantly in recent years, driven by supply chain issues, environmental and social concerns, and

Thermodynamic Partition Function from Quantum Theory for Black Hole Horizons in Loop Quantum Gravity
Advances in High Energy Physics, 2016 We establish the link between the thermodynamics and the quantum theory of black hole horizons through the construction of the thermodynamic partition function, partly based on some physically plausible arguments, by beginning from the description of ...
