Forces Induced by Non-Equilibrium Fluctuations: The Soret-Casimir Effect
arXiv:cond-mat/0308373 · doi:10.1209/epl/i2004-10275-5
Abstract
The notion of fluctuation-induced forces is generalized to the cases where the fluctuations have nonequilibrium origin. It is shown that a net force is exerted on a single flat plate that restricts scale-free fluctuations of a scalar field in a temperature gradient. This force tends to push the object to the colder regions, which is a manifestation of thermophoresis or the Soret effect. In the classic two-plate geometry, it is shown that the Casimir forces exerted on the two plates differ from each other, and thus the Newton's third law is violated.
