The role of quantum measurement in stochastic thermodynamics
npj Quantum Information, 2017 Rebuilding quantum thermodynamics on quantum measurement Measuring a quantum system is an ultimately random operation. It induces a genuinely quantum time arrow, increasing the system’s entropy. But because it perturbs its state, quantum measurement also

Coherence and measurement in quantum thermodynamics. [PDF]
Sci Rep, 2016 Thermodynamics is a highly successful macroscopic theory widely used across the natural sciences and for the construction of everyday devices, from car engines and fridges to power plants and solar cells.

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

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 ...

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,

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

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
