Mesoscopic oscillations of the conductance of disordered metallic   samples as a function of temperature
  We show theoretically and experimentally that the conductance of small disordered samples exhibits random oscillations as a function of temperature. The amplitude of the oscillations decays as a power law of temperature, and their characteristic period is of the order of the temperature itself.
