Dynamical Keldysh model for colored noise and finite relaxation rate

Abstract

The Keldysh model describes quantum dots subjected to Gaussian noise with infinite correlation time. For multi-component noise coupled through non-commuting matrices, the spectrum exhibits a pseudogap. We solve the model for coloured noise with any correlation time, $1/ γ$. Finite memory leads to the pseudogap being filled, its peaks merging and the line narrowing.
