Exciton Condensates are Super!

Speaker:

Allan MacDonald - University of Texas

Electronic systems can have a type of order in which coherence is spontaneously established between two distinct groups of electrons. So far this (particle-hole or exciton condensate) type of order has been found only in double-layer two-dimensional electron gas systems, and only in certain strong magnetic field limits. I will review some of the surprising superconducting transport effects that have already been observed in double-layer exciton condensates, and speculate on others that may be observable in the future.
