TLDR
Theoretically, all different engine types become thermodynamically equivalent in the quantum regime as mentioned in this paper, and it has been shown that the quantum engine types are similar to their macroscopic classical counterparts.Abstract:
Heat machines on the atomic scale are surprisingly similar to their macroscopic classical counterparts. Theorists show that all different engine types become thermodynamically equivalent in the quantum regime.read more

Fundamental aspects of steady-state conversion of heat to work at the nanoscale
TL;DR: In this paper, the authors introduce some of the theories used to describe these steady-state flows in a variety of mesoscopic or nanoscale systems, including linear response theory with or without magnetic fields, Landauer scattering theory in the linear response regime and far from equilibrium.

The role of quantum information in thermodynamics—a topical review
John Goold,Marcus Huber,Marcus Huber,Marcus Huber,Arnau Riera,Lídia del Rio,Paul Skrzypczyk,Paul Skrzypczyk +7 more
TL;DR: This topical review article gives an overview of the interplay between quantum information theory and thermodynamics of quantum systems, including the foundations of statistical mechanics, resource theories, entanglement in thermodynamic settings, fluctuation theorems and thermal machines.

The role of quantum information in thermodynamics --- a topical review
John Goold,Marcus Huber,Marcus Huber,Marcus Huber,Arnau Riera,Lídia del Rio,Paul Skrzypczyk,Paul Skrzypczyk +7 more
TL;DR: In this paper, an overview of the interplay between quantum information theory and thermodynamics of quantum systems is presented. But this is not a comprehensive review of the diverse field of quantum thermodynamics; rather, it is a convenient entry point for the thermo-curious information theorist.

TL;DR: Here, an ensemble of nitrogen vacancy centers in diamond is used for implementing two types of quantum heat engines, and the presence of such internal coherence causes different types of Quantum heat engines to become thermodynamically equivalent.

The extraction of work from quantum coherence
TL;DR: It is shown that for any thermal machine with finite resources not all the coherence of a state can be extracted as work, however, even bounded thermal machines can be reused infinitely many times in the process of work extraction from coherence.

On the Generators of Quantum Dynamical Semigroups
TL;DR: In this paper, the notion of a quantum dynamical semigroup is defined using the concept of a completely positive map and an explicit form of a bounded generator of such a semigroup onB(ℋ) is derived.

Completely Positive Dynamical Semigroups of N Level Systems
TL;DR: In this article, the general form of the generator of a completely positive dynamical semigroup of an N-level quantum system was established, and the result was applied to derive explicit inequalities among the physical parameters characterizing the Markovian evolution of a 2-level system.

Solution of the Schrödinger equation by a spectral method
TL;DR: In this paper, the spectral properties of solutions to the time-dependent Schrodinger equation were used to determine the eigenvalues and eigenfunctions of the Schrodings equation.

Efficiency of a Carnot engine at maximum power output
F. L. Curzon,B. Ahlborn +1 more
TL;DR: In this article, the efficiency of a Carnot engine for the case where the power output is limited by the rates of heat transfer to and from the working substance was analyzed, and it was shown that the efficiency at maximum power output was given by the expression η = 1 − (T2/T1)1/2 where T1 and T2 are the respective temperatures of the heat source and heat sink.
