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…

Fractional-Time Jaynes-Cummings Model: Unitary Description of its Quantum Dynamics, Inverse Problem and Photon Statistics
Thiago T. Tsutsui, Danilo Cius, Antonio S. M. de Castro +1
We analyze the quantum dynamics of the fractional-time Jaynes-Cummings model using a recent unitary framework for the fractional-time Schrödinger equation. We examine how the fract…
