Spectral statistics of disordered metals in the presence of several Aharonov-Bohm fluxes
Abstract
The form factor for spectral correlations in a diffusive metal is calculated in the presence of several Aharonov-Bohm fluxes. When the fluxes φ are equal, the correlations are universal functions of n g2 φ where g is the dimensionless conductance and n is the number of applied fluxes. This explains recent flux dependence of the correlations found numerically at the metal-insulator transition.
