Ultrastrong coupling regimes of light-matter interaction

P Forn-Díaz, L Lamata, E Rico, J Kono, E Solano - Reviews of Modern Physics, 2019 - APS
Recent experiments have demonstrated that light and matter can mix together to an extreme
degree, and previously uncharted regimes of light-matter interactions are currently being …

Breakdown of gauge invariance in ultrastrong-coupling cavity QED

D De Bernardis, P Pilar, T Jaako, S De Liberato, P Rabl - Physical Review A, 2018 - APS
We revisit the derivation of Rabi-and Dicke-type models, which are commonly used for the
study of quantum light-matter interactions in cavity and circuit QED. We demonstrate that the …

Nonperturbative dynamical Casimir effect in optomechanical systems: Vacuum Casimir-Rabi splittings

V Macrì, A Ridolfo, O Di Stefano, AF Kockum, F Nori… - Physical Review X, 2018 - APS
We study the dynamical Casimir effect using a fully quantum-mechanical description of both
the cavity field and the oscillating mirror. We do not linearize the dynamics, nor do we adopt …

Emission of photon pairs by mechanical stimulation of the squeezed vacuum

W Qin, V Macrì, A Miranowicz, S Savasta, F Nori - Physical Review A, 2019 - APS
To observe the dynamical Casimir effect (DCE) induced by a moving mirror is a long-
