Superlattice Quantum Solid of Dipolar Excitons (04/2024)
In the dipolar occupation blockade regime the occupation of lattice sites can not exceed unity. Beyond this average filling here we show that dipolar repulsions spontaneously stabilise spatially ordered quantum matter phases. Precisely, we study indirect excitons confined in an electrostatic lattice of a GaAs bilayer. For an average filling around 1.5 we show that excitons realise a face-centered superlattice quantum solid. Our work further underlines that indirect excitons provide a unique platform in the solid-state for quantum simulations of the Hubbard model.
