Luminescence and photon coherence in superconducting pn-heterostructures — •Patrik Hlobil, Peter Orth, and Jörg Schmalian — Karlsruhe Institute of Technology, Germany

Semiconducting pn-heterostructures coupled to superconducting leads appear to be promising candidates as a source of entangled and squeezed light. Due to an applied bias voltage V, we have to use a non-equilibrium field theory approach to study the electron-photon system. Particular emphasis is placed on the consequence of the superconducting coherence for the photon statistics, the luminescence and possible feedback on the electronic system.
