Semiconductor nanostructures, such as quantum Hall bilayers and semiconductor microcavities, are transistor-like devices in which many exotic ordered electronic states have been observed. In particular, recent experiments have shown the existence of Bose-Einstein condensates of excitons in quantum Hall bilayers, and a Bose-Einstein condensate of polaritons in microcavities. These phenomena will dramatically modify the electrical or optical transport properties of the structures, leading for example to dissipationless electrical transport in the quantum Hall bilayer. This project aims to predict and analyse the results of transport experiments on these systems, using a combination of numerical simulations and analytical studies. Since these transport properties are largely controlled by disorder this requires a significant numerical effort, to obtain good statistics over the random disorder potential.
