Interaction corrections at intermediate temperatures: Longitudinal conductivity and kinetic equation
Interaction corrections at intermediate temperatures: Longitudinal conductivity and kinetic equation
It is well known that electron-electron interaction in two-dimensional disordered systems leads to logarithmically divergent Altshuler-Aronov corrections to conductivity at low temperatures $(T\ensuremath{\tau}\ensuremath{\ll}1;$ $\ensuremath{\tau}$ is the elastic mean-free time). This paper is devoted to the fate of such corrections at intermediate temperatures $T\ensuremath{\tau}\ensuremath{\gtrsim}1.$ We show that in this (ballistic) regime …
