Doubly Dressed Bosons: Exciton Polaritons in a Strong Terahertz Field
Doubly Dressed Bosons: Exciton Polaritons in a Strong Terahertz Field
We demonstrate the existence of a novel quasiparticle, an exciton in a semiconductor doubly dressed with two photons of different wavelengths: a near infrared cavity photon and terahertz (THz) photon, with the THz coupling strength approaching the ultrastrong coupling regime. This quasiparticle is composed of three different bosons, being a …
