Optimizing the classical heat engine [PDF]
Physical Review Letters, 2000 A pair of systems at different temperatures is a classic environment for a heat engine, which produces work during the relaxation to a common equilibrium. It is generally believed that a direct interaction between the two systems will always decrease the

Isolated quantum heat engine [PDF]
Physical Review Letters, 2012 We present a theoretical and numerical analysis of a quantum system that is capable of functioning as a heat engine. This system could be realized experimentally using cold bosonic atoms confined to a double well potential that is created by splitting a ...

Fluctuations in heat engines [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 Abstract At the dawn of thermodynamics, Carnot’s constraint on efficiency of heat engines stimulated the formulation of one of the most universal physical principles, the second law of thermodynamics. In recent years, the field of heat engines acquired a new twist due to enormous efforts to develop and describe microscopic machines based

A sublimation heat engine. [PDF]
Nat Commun, 2015 AbstractHeat engines are based on the physical realization of a thermodynamic cycle, most famously the liquid–vapour Rankine cycle used for steam engines. Here we present a sublimation heat engine, which can convert temperature differences into mechanical work via the Leidenfrost effect.

Autonomous circular heat engine [PDF]
Physical Review E, 2022 A dynamical model of a highly efficient heat engine is proposed, where an applied temperature difference maintains the motion of particles around the circuit consisting of two asymmetric narrow channels, in one of which the current flows against the applied thermodynamic forces.

The power of a critical heat engine. [PDF]
Nat Commun, 2016 AbstractSince its inception about two centuries ago thermodynamics has sparkled continuous interest and fundamental questions. According to the second law no heat engine can have an efficiency larger than Carnot’s efficiency. The latter can be achieved by the Carnot engine, which however ideally operates in infinite time, hence delivers null power.

Optimization of an active heat engine [PDF]
Physical Review E, 2021 Optimisation of heat engines at the micro-scale has applications in biological and artificial nano-technology, and stimulates theoretical research in non-equilibrium statistical physics. Here we consider non-interacting overdamped particles confined by an external harmonic potential, in contact either with a thermal reservoir or with a stochastic self ...

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.

Topological Josephson heat engine [PDF]
Communications Physics, 2020 AbstractTopological superconductors represent a fruitful playing ground for fundamental research as well as for potential applications in fault-tolerant quantum computing. Especially Josephson junctions based on topological superconductors remain intensely studied, both theoretically and experimentally. The characteristic property of these junctions is
