Level crossings and superradiant quantum phase transition for a two-qutrit quantum Rabi model
R. Grimaudo, A. S. M. De Castro, G. Falci +3
A two-qutrit extension of the quantum Rabi model is studied. Despite its increased complexity, the model results to be integrable under specific, physically relevant conditions. Th…

Jaynes-Cummings dynamics in strong coupling for many-interacting-qubit quantum Rabi models
Roberto Grimaudo, Sagnik Chakraborty, Rosario Lo Franco +1
The present work focuses on the strong/weak interaction of many-body spin-systems with a cavity mode. It introduces the necessity of redefining the physical conditions determining…
