Distribution function of the local density of states of a one-channel weakly disordered ring in an external magnetic field
Distribution function of the local density of states of a one-channel weakly disordered ring in an external magnetic field
A real space diagrammatic method, which is an extension of the Berezinskii technique to problems with periodic boundary condition, is formulated to study the density of states (DOS) $\ensuremath{\rho}(\ensuremath{\epsilon},\ensuremath{\varphi})$ and its moments for a one-channel weakly disordered ring threaded by an external magnetic flux $\ensuremath{\varphi}.$ The exact result obtained for …
