"The Memory of Electron Glass":
We investigate theoretically the slow non-exponential relaxation dynamics of electron glasses out of equilibrium, where a sudden change in carrier density leads to interesting memory effects. The self-consistent dynamics of the occupation numbers in the system successfully recovers the general behaviour found in experiments. Our numerical analysis is consistent with both the expected logarithmic relaxation and our understanding of how increasing disorder or interaction slows down the relaxation process, thus yielding a complete picture of electron glass. We also present an unprecedented domino effect where the connection to the leads affects the relaxation process of electron glass in mesoscopic systems, speeding it up, and even reversing the expected effect of interaction, stronger interaction leading to a faster relaxation.
