The quantum Rabi model [1,2,3] describes the interaction between a two-level quantum system and a single bosonic mode. Whereas the regime of ultra-strong coupling (USC) has just been recently investigated, and an experimental realization of the quantum Rabi model in the deep strong coupling (DSC) regime has so far been absent. We propose a setup to perform a full quantum simulation of the quantum Rabi model regarding an effective two-level quantum system, provided by the occupation of Bloch bands by ultra-cold atoms in tailored optical lattices [4], interacting with a quantum harmonic oscillator implemented with an optical dipole trap. This setup will enable us to study the crossover between USC and DSC regimes, where a pattern of collapse and revival is predicted.
