Description of ultrastrong light-matter interaction through coupled harmonic oscillator models and their connection with cavity-QED Hamiltonians
Unai Muniain, Javier Aizpurua, Rainer Hillenbrand +2
Classical coupled harmonic oscillator models are capable of describing the optical and infrared response of nanophotonic systems where a cavity photon couples to dipolar matter exc…

Identifying unbound strong bunching and the breakdown of the Rotating Wave Approximation in the quantum Rabi model
Álvaro Nodar, Ruben Esteban, Unai Muniain +3
We use a recently derived gauge-invariant formulation of the problem of a two-level system coupled to an optical cavity, to explore the transition between the weak, and the ultra-s…
