A three-dimensional superconformal quantum mechanics with dynamical symmetry
Ivan E. Cunha, Francesco Toppan
We construct a three-dimensional superconformal quantum mechanics (and its associated de Alfaro-Fubini-Furlan deformed oscillator) possessing an dynamical symmetry. At a…

On the spectrum-generating superalgebras of the deformed one-dimensional quantum oscillators
N. Aizawa, I. E. Cunha, Z. Kuznetsova +1
We investigate the dynamical symmetry superalgebras of the one-dimensional Matrix Superconformal Quantum Mechanics with inverse-square potential. They act as spectrum-generating su…

Hadronic Matter in the Robertson-Walker Metric and the Early Universe
Ivan E. Cunha, Celso C. Barros
In this work, the Friedman equations for hadronic matter in the Robertson-Walker metric in the early Universe are obtained. We consider the hadronic phase, formed after the hadroni…
