On a Connection Between Nonlinear Response to an External Field and Equilibrium Properties of Systems with Interaction: Comment on cond-mat/9711226 by Kopietz and Voelker

We demonstrate the danger of a naive identification of kinetic coefficients in the free-electron response expansion in powers of an external electric field and coefficients in the expansion of the corresponding equilibrium quantity in powers of the fluctuating intrinsic electric field. A particular example of the direct current generation by an AC electric field in a mesoscopic system of non-interacting electrons vs. the Fock contribution to the equilibrium persistent current in a system of interacting electrons is considered.

Charged Many-Electron -- Single Hole Complexes in a Double Quantum Well near a Metal Plate

It has been shown that the presence of a metal plate near a double quantum well with spatially separated electron and hole layers may lead to a drastic reconstruction of the system state with the formation of stable charged complexes of several electrons bound to a spatially separated hole. Complexes of both the Fermi and the Bose statistics may coexist in the ground state and their relative densities may be changed with the change of the electron and hole densities. The stability of the charged complexes may be increased by an external magnetic field perpendicular to the layers plane.
