Quantum heat engine with continuum working medium [PDF]
J. Phys. A 40, 8655-8664 (2007), 2006 We introduce a new quantum heat engine, in which the working medium is a quantum system with a discrete level and a continuum. Net work done by this engine is calculated and discussed. The results show that this quantum heat engine behaves like the two-level quantum heat engine in both the high-temperature and the low-temperature limits, but it ...

Holographic Heat Engines as Quantum Heat Engines [PDF]
Class. Quant. Grav. 37, 034001 (2019), 2019 Certain solutions of Einstein's equations in anti-de Sitter spacetime can be engineered, using extended gravitational thermodynamics, to yield `holographic heat engines', devices that turn heat into useful mechanical work. On the other hand, there are constructions (both experimental and theoretical) where a series of operations is performed on a small

Information Arbitrage in Bipartite Heat Engines [PDF]
Physical Review X, 2023 Heat engines and information engines have each historically served as motivating examples for the development of thermodynamics. While these two types of systems are typically thought of as two separate kinds of machines, recent empirical studies of ...

Solutions and Heat Engines [PDF]
Nature, 1929 IT is not usual for an author to complain of a review of his book; but I confess that the theory of osmotic pressure put forward (in place of an account of my own reasoning) by the reviewer, in NATURE of Feb. 16, of my book “Gases and Liquids”, almost took my breath away. As the reviewer's reply, in NATURE of Mar. 9, to Prof.

Relativistic quantum heat engine from uncertainty relation standpoint. [PDF]
Sci Rep, 2019 Established heat engines in quantum regime can be modeled with various quantum systems as working substances. For example, in the non-relativistic case, we can model the heat engine using infinite potential well as a working substance to evaluate the ...

Designing a highly efficient graphene quantum spin heat engine. [PDF]
Sci Rep, 2019 We design a quantum spin heat engine using spin polarized ballistic modes generated in a strained graphene monolayer doped with a magnetic impurity. We observe remarkably large efficiency and large thermoelectric figure of merit both for the charge as well as spin variants of the quantum heat engine.

Superradiant Quantum Heat Engine. [PDF]
Sci Rep, 2015 AbstractQuantum physics revolutionized classical disciplines of mechanics, statistical physics and electrodynamics. One branch of scientific knowledge however seems untouched: thermodynamics. Major motivation behind thermodynamics is to develop efficient heat engines.

Nonlinear effects for three-terminal heat engine and refrigerator. [PDF]
Sci Rep, 2018 The three-terminal heat device that consists of an electronic cavity and couples to a heat bath is studied both as a heat engine and as a refrigerator. We investigate the characteristic performance in the linear and nonlinear regime for both setups.

Efficient and tunable Aharonov-Bohm quantum heat engine [PDF]
Physical review B, 2019 We propose a quantum heat engine based on an Aharonov-Bohm interferometer in a two-terminal geometry, and investigate its thermoelectric performances in the linear response regime.
