Meanfield theory for the spintriplet excition liquid in quantum wells
Abstract
Using a meanfield theory, we study the possible existence of a spintriplet intersubband exciton liquid ground state in semiconductor quantum well systems as a function of the electronic density and the strength of the intersubband Coulomb interaction matrix element at low temperatures. We find the excitonic phase to be stable over a large region of parameter space, and our calculated critical temperatures are attainable experimentally. In addition, we find that the transition to the excitonic phase can be either first or secondorder at zero temperature.
