Nonlinear optical behavior of confined electrons under torsion and magnetic fields
Carlos Magno O. Pereira, Edilberto O. Silva
In this work, we investigate the influence of torsion, Aharonov-Bohm flux, and external magnetic fields on the linear and nonlinear optical properties of a confined quantum system.…
Quantum Hall-like effect for neutral particles with magnetic dipole moments in a quantum dot
Carlos Magno O. Pereira, Edilberto O. Silva
We predict a new class of quantum Hall phenomena in completely neutral systems, demonstrating that the interplay between radial electric fields and dipole moments induces exact $e^…
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…
Rotating effects on the Hall conductivity in a quantum dot
Carlos Magno O. Pereira, Luís Fernando C. Pereira, Denise Assafrão +1
We investigate the behavior of the quantized Hall conductivity in a two-dimensional quantum system under rotating effects, a uniform magnetic field, and an Aharonov-Bohm (AB) flux…
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…
