Stochastic thermodynamics as reviewed here systematically provides a framework for
extending the notions of classical thermodynamics such as work, heat and entropy …

Electron ratchets are non-equilibrium electronic devices that break inversion symmetry to
produce currents from non-directional and random perturbations, without an applied net …

This article is an accessible introduction to ratchets and their potential uses. A ratchet can
dramatically improve directional transport of classical or quantum particles in systems that …

We compute the entropy reduction in feedback controlled systems due to the repeated
operation of the controller. This was the lacking ingredient to establish the thermodynamics …

The sum of the average work dissipated plus the information gained during a
thermodynamic process with discrete feedback must exceed zero. We demonstrate that the …

A flashing ratchet transports diffusive particles using a time-dependent, asymmetric
potential. The particle speed is predicted to increase when a feedback algorithm based on …

Here, we investigate the uncertainty of dynamical observables in classical systems
manipulated by repeated measurements and feedback control; the precision should be …

The purpose of this study is to investigate the Brownian heat engine with thermo-ecological
function (ECF) and ecological coefficient of performance (ECOP). Potential and kinetic heat …

It was recently shown that the use of feedback control can improve the performance of a
flashing ratchet. We investigate the effect of a time delay in the implementation of feedback …

Brownian particles moving in a spatially asymmetric but periodic potential (ratchet), with an
external load force and connected to an alternating hot and cold reservoir, are modeled as a …
