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…
Analytical Solutions of One-Dimensional () Potentials for Spin-0 Particles via the Feshbach-Villars Formalism
Abdelmalek Boumali, Abdelmalek Bouzenada, Edilberto O. Silva
We present a unified analytical and numerical study of the one-dimensional Feshbach--Villars (FV) equation for spin-0 particles in the presence of several representative external p…
Numerical study of non-relativistic quantum systems and small oscillations induced in a helically twisted geometry
C. F. S. Pereira, R. L. L. Vitória, A. R. Soares +3
We investigate bound states of a non-relativistic scalar particle in a three-dimensional helically twisted (torsional) geometry, considering both the free case and the presence of…
Quantum scattering in helically twisted geometries: Coulomb-like interaction and Aharonov-Bohm effect
Augusto Tadeu P. de Araújo, Edilberto O. Silva
We investigate the scattering of a charged quantum particle in a helically twisted background that induces an effective Coulomb-like interaction, in the presence of an Aharonov-Boh…
Bounds on Lorentz-violating parameters in magnetically confined 2D systems: A phenomenological approach
Edilberto O. Silva
We present a unified, SI-consistent framework to constrain minimal SME coefficients and using magnetically confined two-dimensional electron systems under a uniform mag…
