Topological control of third-harmonic generation in a mesoscopic quantum ring with spiral dislocation
Carlos Magno O. Pereira, Denise Assafrão, Edilberto O. Silva
We investigate the nonlinear optical response of a two-dimensional mesoscopic quantum ring subjected to a spiral dislocation, with emphasis on third-harmonic generation (THG). The…
Torsion-controlled spin transport and tunable intersubband absorption in a screw-dislocated semiconductor nanowire
Carlos Magno O. Pereira, Edilberto O. Silva
We develop an effective-mass theory for spin-resolved transport and intersubband optical absorption in a finite semiconductor nanowire containing a uniform screw-dislocation-induce…
Torsion-induced confinement and tunable nonlinear optical gain in a mesoscopic electron system
Carlos Magno O. Pereira, Edilberto O Silva
We investigate the optical response of a conduction electron in a helically twisted mesoscopic medium containing a screw dislocation and a uniform torsional background, in the pres…
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…
Remarks on the Study of Electronic Properties and Photoionization Process in Rotating 2D Quantum Rings
Carlos Magno O. Pereira, Frankbelson dos S. Azevedo, Edilberto O. Silva
Electronic and optical properties of a mesoscopic heterostructure of a two-dimensional quantum ring composed of Gallium Arsenide (GaAs) semiconductors are investigated. Using the c…
Rotating effects on the photoionization cross-section of a 2D quantum ring
Carlos Magno O. Pereira, Frankbelson dos S. Azevedo, Luís Fernando C. Pereira +1
In this letter, we investigate the nonrelativistic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov-Bohm (AB) effect and a uniform mag…
