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…
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…
Green's function approach for quantum graphs: an overview
Fabiano M. Andrade, A. G. M. Schmidt, E. Vicentini +2
Here we review the many aspects and distinct phenomena associated to quantum dynamics on general graph structures. For so, we discuss such class of systems under the energy domain…
