Detecting Josephson effect in the excitonic condensate by coherent emission of light
Abstract
Description
Coherent emission of light by a split excitonic Bose-Einstein condensate -- excitonic Josephson junction -- can be extremely sensitive to the Josephson phase established across the junction. As a result of this, the emission can be redistributed between different directions and even cancelled. The cases of the dipole- and of the quadrupole-active excitons are considered.
