Proposed cavity Josephson plasmonics with complex-oxide heterostructures

Year: 2016

Type: article

Abstract: We discuss how complex-oxide heterostructures that include high-${T}_{c}$ superconducting cuprates can be used to realize an array of submillimeter cavities that support Josephson plasmon polaritons. These cavities have several attractive features for new types of light-matter interaction studies and we show that they promote ``ultrastrong'' coupling between THz frequency radiation and Josephson plasmons. Cavity electrodynamics of Josephson plasmons allows us to manipulate the superconducting order-parameter phase coherence. As an example, we discuss how it could be used to cool superconducting phase fluctuations with light.
