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…

Thermodynamic Limit in the Two-qubit Quantum Rabi Model with Spin-Spin Coupling
R. Grimaudo, G. Falci, A. Messina +4
The occurrence of a second-order superradiant quantum phase transition is brought to light in a quantum system consisting of two interacting qubits coupled to the same quantized fi…

Landau-Majorana-Stuckelberg-Zener dynamics driven by coupling for two interacting qutrit systems
R. Grimaudo, N. V. Vitanov, A. Messina
A time-dependent two interacting spin-qutrit model is analysed and solved. The two interacting qutrits are subjected to a longitudinal field linearly varying over time as in the La…
