On Classical Fluctuations of Ballistic Conductance
arXiv:cond-mat/0406206
Abstract
Universal conductance fluctuations in disordered systems are one of the most known quantum mesoscopic effects. For ballistic cavity with smooth confining potential however, one should observe a much larger classical sample-to-sample conductance fluctuations. It is shown, how bending of the phase space in case of chaotic dynamics leads to additional enhancement of such fluctuations.
