Title: Ising model for a Brownian donkey
Authors: CLEUREN, Bart
Issue Date: 2001
Publisher: E D P SCIENCES
Citation: EUROPHYSICS LETTERS, 54(1). p. 1-6
Abstract: We introduce a thermal engine consisting of N interacting Brownian particles moving in a periodic potential, featuring an alternation of hot and cold symmetric peaks. A discretized Ising-like version is solved analytically. In response to an external force, absolute negative mobility is observed for N greater than or equal to 4. For N --> infinity nonequilibrium phase transition takes place with a spontaneous symmetry breaking en ailing he appearance of a current in the absence of an external force.
