A Gross-Pitaevskii theory for an excitonic incompressible Bose solid
Sara Conti, Andrey Chaves, Alexander R. Hamilton +3
We show that interlayer excitons in double-layer semiconductor heterostructures can form a Bose solid, which is an incompressible supersolid characterized by exactly one boson per…

Beyond Random Phase Approximation in electron-hole bilayer superfluidity
Filippo Pascucci, Stefania De Palo, Sara Conti +3
We derive the normal and anomalous proper polarization functions and the screened Coulomb interactions in a two-dimensional superfluid electron-hole bilayer, including all first-or…
