Low-Temperature Dephasing in Disordered Conductors: the Effect of ``1/f'' Fluctuations
Abstract
Electronic quantum effects in disordered conductors are controlled by the dephasing rate of conduction electrons. This rate is expected to vanish with the temperature. We consider the very intriguing recently reported apparent saturation of this dephasing rate in several systems at very low temperatures. We show that the ``standard model'' of a conductor with static defects can not have such an effect. However, allowing some dynamics of the defects may produce it.
