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 $\varphi$ are equal, the correlations are universal functions of $n{g}^2\varphi$ 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.
