Abstract:
The persistent current in a mesoscopic ring has a Gaussian distribution with
small non-Gaussian corrections. Here we report a semiclassical calculation of
the leading non-Gaussian correction, which is described by the three-point
correlation function. The semiclassical approach is applicable to systems in
which the electron dynamics is ballistic and chaotic, and includes the
dependence on the Ehrenfest time. At small but finite Ehrenfest times, the
non-Gaussian fluctuations are enhanced with respect to the limit of zero
Ehrenfest time.
