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…
Dynamics of massive and massless particles in the spacetime of a wiggly cosmic dislocation
Frankbelson dos S. Azevedo, Edilberto O. Silva
In this paper, we investigate the spacetime containing both small-scale structures (wiggles) and spatial dislocation, forming a wiggly cosmic dislocation. We study the combined eff…
An optical wormhole from hollow disclinations
Frankbelson dos S. Azevedo, José Diêgo M. de Lima, Antônio de Pádua Santos +1
We examine the optical properties of two different configurations of an ordered liquid crystal film on a catenoid forming coreless disclinations. We find the effective optical metr…
