Gaussian work extraction from random Gaussian states is nearly impossible
Physical Review Research, 2023 Quantum thermodynamics can be naturally phrased as a theory of quantum state transformation and energy exchange for small-scale quantum systems undergoing thermodynamical processes, thereby making the resource theoretical approach very well suited. A key

Probabilistically violating the first law of thermodynamics in a quantum heat engine
SciPost Physics, 2022 Fluctuations of thermodynamic observables, such as heat and work, contain relevant information on the underlying physical process. These fluctuations are however not taken into account in the traditional laws of thermodynamics. While the second law is

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

Thermodynamics of precision in quantum nanomachines [PDF]
Physical Review E, 2021 Fluctuations strongly affect the dynamics and functionality of nanoscale thermal machines. Recent developments in stochastic thermodynamics have shown that fluctuations in many far-from-equilibrium systems are constrained by the rate of entropy production via so-called thermodynamic uncertainty relations.

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 ...

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.

Correlated catalyst in quantum thermodynamics [PDF]
Europhysics lettersIn this short review article, we present recent progress in quantum thermodynamics in the framework with a correlated catalyst. We examine two key properties of thermal operations, the Gibbs-preserving property and the covariant property.

Thermodynamics of quantum crystalline membranes [PDF]
Physical Review B, 2014 We investigate the thermodynamic properties and the lattice stability of two-dimensional crystalline membranes, such as graphene and related compounds, in the low temperature quantum regime $T\rightarrow0$. A key role is played by the anharmonic coupling between in-plane and out-of plane lattice modes that, in the quantum limit, has very different ...

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 ...

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,
