Query: Thermally Assisted Current-Driven Skyrmion Motion   We study the behavior of skyrmions in thin films under the action of
stochastic torques arising from thermal fluctuations. We find that the Brownian
motion of skyrmions is described by a stochastic Thiele's equation and its
corresponding Fokker-Planck equation. The resulting Fokker-Planck equation is
recognized as the one for a high-friction Brownian particle which has been
studied extensively in different physical contexts. It is shown that thermal
fluctuations favor the skyrmion motion allowing a finite mobility even in
presence of pinning traps. We calculate explicitly the mobility tensor of
skyrmions in linear response to an electric current finding that it increases
with temperature.
