The Feynman ratchet-and-pawl revisited

by Prof. Bart Cleuren (Hasselt University)

Europe/Stockholm
Description

The Feynman ratchet-and-pawl is a celebrated illustration of an apparent Maxwell demon, capable of extracting useful work from equilibrium thermal fluctuations. In this talk I review the original context of the ratchet-and-pawl construction and present a microscopic exact conceptualisation, allowing for a discussion based on first principles.
