Query: Experimental conditions for observation of electron-hole superfluidity
  in GaAs heterostructures   The experimental parameter ranges needed to generate superfluidity in optical
and drag experiments in GaAs double quantum wells are determined, using a
formalism that includes self-consistent screening of the Coulomb pairing
interaction in the presence of the superfluid. The very different electron and
hole masses in GaAs make this a particularly interesting system for
superfluidity, with exotic superfluid phases predicted in the BCS-BEC crossover
regime. We find that the density and temperature ranges for superfluidity cover
the range for which optical experiments have observed indications of
superfluidity, but that existing drag experiments lie outside the superfluid
range. However we also show that for samples with low mobility with no
macroscopically connected superfluidity, if the superfluidity survived in
randomly distributed localized pockets, standard quantum capacitance
measurements could detect these pockets.
