Heat-exchange statistics in driven open quantum systems
TLDR
In this article, a generalized master equation approach was proposed to calculate the probability distribution of energy exchanges between a periodically driven quantum system and a thermalized heat reservoir, and the authors obtained a universal expression for the distribution, providing clear physical insight into the exchanged energy quanta.Abstract:
As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects. While the statistical mechanics of small classical systems is relatively well understood, the quantum case still poses challenges. Here, we set up a formalism that allows us to calculate the full probability distribution of energy exchanges between a periodically driven quantum system and a thermalized heat reservoir. The formalism combines Floquet theory with a generalized master equation approach. For a driven two-level system and in the long-time limit, we obtain a universal expression for the distribution, providing clear physical insight into the exchanged energy quanta. We illustrate our approach in two analytically solvable cases and discuss the differences in the corresponding distributions. Our predictions could be directly tested in a variety of systems, including optical cavities and solid-state devices.read more

Perspective: Quantum Thermodynamics
James Millen,André Xuereb +1 more
TL;DR: Recently, there has been a surge of interest in exploring the quantum regime, where the origin of fluctuations is quantum rather than thermal as discussed by the authors, leading to the development of quantum heat engines and refrigerators, as well as to vitally needed simple descriptions of quantum many-body systems.

Cavity-assisted quantum bath engineering
TL;DR: In this article, the authors demonstrate quantum bath engineering for a superconducting artificial atom coupled to a microwave cavity by tailoring the spectrum of microwave photon shot noise in the cavity, creating a dissipative environment that autonomously relaxes the atom to an arbitrarily specified coherent superposition of the ground and excited states.
