In contact with nonequilibrium


We discuss how contact with a nonequilibrium bath can modify the effective dynamics of a probe.
In particular, systematic forces may become nongradient; the second fluctuation-dissipation relation
can be broken and the noise may be nonGaussian and showing power law distributed jumps.
