Continuous limit of the square well problem in quantum mechanics
Matheus D. Moro, Thiago T. Tsutsui, Antonio S. M. de Castro +1
The paper demonstrates how the solutions of the quantum square‑well potential converge to free‑particle solutions as the well width becomes infinite, using a Fourier‑transform base…
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 frac…
High Efficiency Storage of Quasi-Classical and Quantum States in Coupled Resonators
Luiz O. R. Solak, Ciro M. Diniz, Daniel Z. Rossatto +3
We propose an optical model in which both quantum and quasi-classical states can be ideally stored using coupled resonators. The protocol is based on a time-dependent coupling betw…
