Hunting for Maxwell's Demon in the Wild
Johan du Buisson, Jannik Ehrich, Matthew P. Leighton +4
The paradox of Maxwell's demon motivated the development of information thermodynamics and the creation of nanoscale information engines. We now understand that machines such as th…
Adding noise and scaling forces to speed up the Langevin clock
Prithviraj Basak, Stephen Whitelam, John Bechhoefer
Using experiments on a colloidal particle trapped in an optical tweezer, we confirm a recent proposal to increase the effective mobility or clock rate of systems described by Lange…
Harnessing higher-dimensional fluctuations in an information engine
Antonio Patrón Castro, John Bechhoefer, David A. Sivak
We study the optimal performance of an information engine consisting of an overdamped Brownian bead confined in a controllable, -dimensional harmonic trap and additionally subje…
Speedups in nonequilibrium thermal relaxation: Mpemba and related effects
Gianluca Teza, John Bechhoefer, Antonio Lasanta +2
Most of our intuition about the behavior of physical systems is shaped by observations at or near thermal equilibrium. However, even a thermal quench can lead to states far from th…
Performance limits of information engines
Johan du Buisson, David A. Sivak, John Bechhoefer
We review recent studies of a colloidal information engine that consists of a bead in water and held by an optical trap. The bead is ratcheted upward without any apparent external…
