Fluctuations in Mesoscopic Insulators: The replica Cooperon and Diffsuson — •Rangel Rafael1 and Ernesto Medina2 — 1ICA1, Univ. Stuttgart, Pfaffenwaldring 27, 70569 Stuttgart, Germany — 2Dpto. de Fisica, Univ. Simon Bolivar, Caracas, Venezuela
We explore mesoscopic fluctuations in the insulating regime within the Nguyen, Spivak and Shklovskii model. We find the fluctuations persist above the decorreltion field. We use the replica approach to derive the No-dqcooperonNo-dq and No-dqdiffusonNo-dq analogs of the weak localization regime.
