In this paper we discuss the microscopic physics of these states and recent progress toward building a theory of the anomalous collective transport effects that occur in separately contacted bilayers when the condensate is present.6 pages, ICPS 2002 Conference ProceedingsMesoscale and Nanoscale PhysicsStrongly Correlated Electronstext
