Exact treatment of rotation-induced modifications in two-dimensional quantum rings
Carlos Magno O. Pereira, Frankbelson dos S. Azevedo, Edilberto O. Silva
We investigate the influence of rotation on the Fermi energy, magnetization, and persistent current in two-dimensional quantum rings. Using the Tan-Inkson confinement potential and…

Modifications in the photoionization cross-section of a quantum dot with position-dependent effective mass
Carlos Magno O. Pereira, Denise Assafrão, Frankbelson dos S. Azevedo +3
In this work, we investigate the photoionization cross-section of an electron confined in a quantum dot, considering the position-dependent variation of the effective mass through…

Fermions in -dimensions modified by nonminimal coupling and its applications to condensed matter physics
J. A. A. S. Reis, L. Lisboa-Santos, Fabiano M. Andrade +2
Fermions in two-dimensional space, commonly called -dimensional fermions, exhibit intriguing and distinctive characteristics that distinguish them from their higher-dimensio…
