Query: Exciton condensate in semiconductor quantum well structures.   We propose that the exciton condensate may form in a well-controlled way in
appropriately arranged semiconductor quantum well structures. The mean-field
theory of Keldysh and Kopaev, exact in both the high density and the low
density limits, is solved numerically to illustrate our proposal. The
electron-hole pairing gap and the excitation spectrum of the exciton condensate
are obtained. The energy scales of the condensate are substantial at higher
densities. We discuss how such densities could be achieved experimentally by
generating an effective pressure.
