Gauge invariance of the Dicke and Hopfield models
Luigi Garziano, Alessio Settineri, Omar Di Stefano +2
The Dicke model, which describes the dipolar coupling between N two-level atoms and a quantized electromagnetic field, seemingly violates gauge invariance in the presence of ultras…

Many-body and correlation effects on parametric polariton amplificazion in semiconductor microcavities
S. Savasta, O. Di Stefano, R. Girlanda
Very efficient amplification of light-matter waves (polaritons), that are a superposition of cavity photons and excitons [1] has recently been reported[2-11]. The optical gain curv…
