摘要：
We consider the weak localization in a ring connected to reservoirs through leads of finite length and submitted to a magnetic field. The effect of decoherence due to electron-electron interaction on the harmonics of Al'tshuler-Aronov-Spivak [JETP Lett. 33, 94 (1981)] oscillations is studied, and more specifically the effect of the leads. Two results are obtained for short and long lead regimes. The scale at which the crossover occurs is discussed. The long lead regime is shown to be more realistic experimentally.
