Influence of a Pseudo Aharonov-Bohm field on the quantum Hall effect in Graphene
Cleverson Filgueiras, Rosinildo Fidelis, Diego Cogollo +1
The effect of an Aharonov-Bohm (AB) pseudo magnetic field on a two dimensional electron gas in graphene is investigated. We consider it modeled as in the usual AB effect but since…
Scattering and bound states of Dirac Equation in presence of cosmic string for Hulthén potential
Mansoureh Hosseinpour, Fabiano M. Andrade, Edilberto O. Silva +1
In this work we study the Dirac equation with vector and scalar potentials in the spacetime generated by a cosmic string. Using an approximation for the centrifugal term, a solutio…
Quantum motion of a spinless particle in curved space: A viewpoint of scattering theory
Fabiano M. Andrade, Augusto R. Chumbes, Cleverson Filgueiras +1
In this work, we study the scattering of a spinless charged particle constrained to move on a curved surface in the presence of the Aharonov-Bohm potential. We begin with the equat…
Landau quantization, Aharonov-Bohm effect and two-dimensional pseudoharmonic quantum dot around a screw dislocation
Cleverson Filgueiras, Moisés Rojas, Gilson Aciole +1
In this paper, we investigate the influence of a screw dislocation on the energy levels and the wavefunctions of an electron confined in a two-dimensional pseudoharmonic quantum do…
Relativistic Quantum Dynamics on a Double Cone
Felipe Gomes, Edilberto Silva, Jonas Lima +2
In this paper, we study the relativistic quantum problem of a particle constrained to a double cone surface. For this purpose, we build the Dirac equation in a curved space using t…
Scattering and bound states of a spin--1/2 neutral particle in the cosmic string spacetime
Fabiano M. Andrade, Cleverson Filgueiras, Edilberto O. Silva
In this paper the relativistic quantum dynamics of a spin-1/2 neutral particle with a magnetic moment in the cosmic string spacetime is reexamined by applying the von Neumann t…
