Lorentz-violating effects in the spin-1/2 Aharonov-Casher problem
Edilberto O. Silva, Fabiano M. Andrade
The effects of a Lorentz symmetry violating background vector on the Aharonov-Casher bound and scattering scenarios is considered. Using an approach based on the self-adjoint exten…
On planar quantum dynamics of a magnetic dipole moment in the presence of electric and magnetic fields
Edilberto O. Silva
The planar quantum dynamics of a neutral particle with a magnetic dipole moment in the presence of electric and magnetic fields is considered. The criteria to establish the planar…
The 2D -Dirac oscillator
Fabiano M. Andrade, Edilberto O. Silva
In this Letter, 2D Dirac oscillator in the quantum deformed framework generated by the -Poincaré-Hopf algebra is considered. The problem is formulated using the -deformed Dir…
Remarks on the Dirac oscillator in dimensions
Fabiano M. Andrade, Edilberto O. Silva
In this work the Dirac oscillator in dimensions is considered. We solve the problem in polar coordinates and discuss the dependence of the energy spectrum on the spin param…
Influence of spatially varying pseudo-magnetic field on a 2D electron gas in graphene
L. G. da Silva Leite, D. Cogollo, C. Filgueiras +1
The effect of a varying pseudo-magnetic field, which falls as , on a two dimensional electron gas in graphene is investigated. By considering the second order Dirac equation…
Effects of spin on the dynamics of the 2D Dirac oscillator in the magnetic cosmic string background
Fabiano M. Andrade, Edilberto O. Silva
In this work the dynamics of a 2D Dirac oscillator in the spacetime of a magnetic cosmic string is considered. It is shown that earlier approaches to this problem have neglected a…
