We calculate a quantum (Casimir-like) superconducting phase-dependent force acting on a movable scatterer
in a superconductor–normal metal–superconductor (SNS) junction. Repulsive Casimir forces are predicted for a
short SNS junction with nonequilibrium (inverse) populations of Andreev levels. In a long SNS junction an
anomalous (nonmonotonic) temperature behavior of quantum force is found.
