A neural-network Maxwell's demon learns cold damping for work extraction
Stephen Whitelam, Sergio Ciliberto, Ludovic Bellon
We train a neural-network Maxwell's demon to extract work from a model of an underdamped micromechanical cantilever subject to thermal noise. The demon, which periodically adjusts…
First passage time distribution in underdamped harmonic oscillators
Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +2
We derive the distribution of the first passage time for the position of an underdamped harmonic oscillator to overcome a threshold . As the distribution…
First passage time for an underdamped harmonic oscillator and application to the power of an information engine
Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +2
The distribution of the first passage time for the position to overcome a threshold is calculated in an underdamped harmonic oscillator. The proof combines sever…
Fluctuation theorems with optical tweezers: theory and practice
Thalyta T. Martins, André H. A. Malavazi, Lucas P. Kamizaki +4
Fluctuation theorems, such as the Jarzynski equality and the Crooks relation, are effective tools connecting non-equilibrium work statistics and equilibrium free energy differences…
Information engine fueled by first-passage times
Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +3
Using a mechanical cantilever submitted to electrostatic feedback control, we investigate the thermodynamic properties of an information engine that extracts work from thermal fluc…
Experimental evidence for strong emergent correlations between particles in a switching trap
Marco Biroli, Sergio Ciliberto, Manas Kulkarni +3
We experimentally study a system of two-dimensional Brownian particles, each confined in a harmonic trap with identical stiffness. The stiffness switches simultaneously bet…
