Abstract
Using an adiabatic approximation, we derive an effective interaction potential for spatially indirect excitons in quantum well structures. Using this potential and path integral Monte Carlo simulations, we study exciton crystallization and the quantum melting phase transition in a macroscopic system of 2D excitons. Furthermore, the superfluid fraction is calculated as a function of density and is shown to vanish upon crystallization.
