Editor’s summaryA pair of two-dimensional (2D) systems, one featuring electron carriers and the other hole carriers, separated by a thin insulating layer can host correlated interlayer excitons. Such excitons are predicted to exhibit superfluidity, as well as the so-called perfect Coulomb drag, in which the current in one layer causes an equal but opposite current in the other layer.
