On the 2D Dirac oscillator in the presence of vector and scalar potentials in the cosmic string spacetime in the context of spin and pseudospin symmetries
Daniel F. Lima, Fabiano M. Andrade, Luis B. Castro +2
The Dirac equation with both scalar and vector couplings describing the dynamics of a two-dimensional Dirac oscillator in the cosmic string spacetime is considered. We derive the D…
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…
Effects of quantum deformation on the integer quantum Hall effect
Fabiano M. Andrade, Edilberto O. Silva, Denise Assafrão +1
In this work an application of the --deformed algebra in condensed matter physics is presented. Starting by the --deformed Dirac equation we study the relativistic generaliza…
Relativistic quantum dynamics of neutral particle in external electric fields: An approach on effects of spin
F. S. Azevedo, Edilberto O. Silva, Luis B. Castro +2
The planar quantum dynamics of spin-1/2 neutral particle interacting with electrical fields is considered. A set of first order differential equations are obtained directly from th…
On the Aharonov-Casher scattering in a CPT-odd Lorentz-violating background
F. M. Andrade, E. O. Silva, T. Prudêncio +1
The effects of a Lorentz symmetry violating background vector on the Aharonov-Casher scattering in the nonrelativistic limit is considered. By using the self-adjoint extension meth…
Quantum harmonic oscillator for dipoles
Cleverson Filgueiras, D. Cogollo, E. O. Silva
In this work we investigate which radial field configuration yields bound states for neutral particles showing non-zero magnetic and electric dipole moments. The main result is tha…
Open string with a background B-field as the first order mechanics, noncommutativity and soldering formalism
A. A. Deriglazov, C. Neves, W. Oliveira +3
To study noncommutativity properties of the open string with constant B-field we construct a mechanical action which reproduces classical dynamics of the string sector under consid…
