On Classical Fluctuations of Ballistic Conductance
  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.
