At the Dutch Research School for Theoretical Physics AIO/OIO School for Statistical Physics and Theory of Condensed Matter (aka the DRSTP SPTCM School 2010) I gave the following presentation on flux quantization in the exciton double layers. Note that this talk is aimed at a theoretical PhD-students level.
