We calculate the temperature dependence of correlations in coupled quantum wells using an STLS formalism generalized to finite temperatures. We investigate the effects of the temperature dependence of the correlations on the acoustic and optical plas

We present a microscopic many-body calculation investigating the competition between the charge density wave and exciton formation in coupled electron–hole layer systems at finite temperature. We find that as the layer separation is decreased there

We investigate the influence of many-body correlations on Coulomb drag between spatially separated conducting layers of electrons. We show that the correlations enhance the drag particularly strongly at low electron densities but cannot be ignored ev

Superfluid ground state in the electron-hole double layer systems is investigated within the mean field approach at zero temperature. The single particle excitation spectrum is obtained for various densities and barrier widths separating the layers.

A system comprising of two adjacent layers of conduction electrons or alternatively a layer of electrons and a layer of holes can exhibit novel instabilities in the liquid phase towards inhomogeneous ground states. The carriers in the two layers can

We have investigated the properties of the collective modes of the two dimensional electron liquid in regions of phase space near the Wigner phase transition. We used a new method which we have recently developed for dealing with the strongly correla

There has been a great deal of interest recently in systems consisting of two parallel layers of electron or hole liquids trapped in adjacent quantum wells of a semiconductor heterostructure. Recently it has been reported that the densities in the tw

In strongly interacting electron systems the buildup of correlations can fundamentally alter the nature of the states of the system compared with the metallic systems. Since the strength of the correlations is determined from the competition between

Two layers of electrons or holes trapped at the adjacent interfaces of a gallium arsenide heterostructure can interact through the Coulomb interaction; this leads to a rich phase diagram of ground states, some of which are inhomogeneous in density. T
