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.

Thermodynamics of Quantum Feedback Cooling [PDF]
Entropy, 2016 The ability to initialize quantum registers in pure states lies at the core of many applications of quantum technologies, from sensing to quantum information processing and computation. In this paper, we tackle the problem of increasing the polarization bias of an ensemble of two-level register spins by means of joint coherent manipulations, involving ...

Verification of Information Thermodynamics in a Trapped Ion System
Entropy, 2022 Information thermodynamics has developed rapidly over past years, and the trapped ions, as a controllable quantum system, have demonstrated feasibility to experimentally verify the theoretical predictions in the information thermodynamics.

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

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 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.

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,

Exploring quantum thermodynamics with NMR
Journal of Magnetic Resonance Open, 2023 Quantum thermodynamics seeks to extend non-equilibrium stochastic thermodynamics to small quantum systems where non-classical features are essential to its description.
