Geometry-induced Coulomb-like potential in helically twisted quantum systems
Frankbelson dos S. Azevedo, Faizuddin Ahmed, Edilberto O. Silva
In this paper, we investigate the Schrödinger equation in a three-dimensional helically twisted space characterized by a non-trivial torsion parameter. By applying exact separation…
Helically twisted spacetime: study of geometric and wave optics, and physical analysis
Edilberto O. Silva, Frankbelson dos S. Azevedo, Faizuddin Ahmed
We analyse a stationary, cylindrically symmetric spacetime endowed with an intrinsic helical twist, . Solving the E…
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…
Optical concentrator from a hyperbolic liquid crystal metamaterial
Frankbelson dos S. Azevedo, David Figueiredo, Fernando Moraes +2
We examine the optical properties of two different configurations of a cylindrical device made from a hyperbolic metamaterial with optical axis defined by circular and radial direc…
The wiggly cosmic string as a waveguide for massless and massive fields
Frankbelson dos S. Azevedo, Fernando Moraes, Francisco Mireles +2
We examine the effect of a wiggly cosmic string for both massless and massive particle propagation along the string axis. We show that the wave equation that governs the propagatio…
