Inertial-Hall effect: the influence of rotation on the Hall conductivity

- Júlio Brandão, F. Moraes, M. Cunha, J. Lima, C. Filgueiras
- Physics
- 2 March 2015

Inertial effects play an important role in classical mechanics but have been largely overlooked in quantum mechanics. Nevertheless, the analogy between inertial forces on mass particles and… Expand

Electron on a cylinder with topological defects in a homogeneous magnetic field

- C. Filgueiras, B. D. Oliveira
- Physics
- 4 November 2011

In this work we study the effects of the geometry and topology of a cylinder on the energy levels of an electron moving in a homogeneous magnetic field. We consider the existence of topological… Expand

Quantum motion of a point particle in the presence of the Aharonov--Bohm potential in curved space

- E. Silva, S. Ulhoa, F. M. Andrade, C. Filgueiras, R. G. G. Amorin
- Physics, Mathematics
- 25 February 2015

The nonrelativistic quantum dynamics of a spinless charged particle in the presence of the Aharonov--Bohm potential in curved space is considered. We chose the surface as being a cone defined by a… Expand

On the quantum dynamics of a point particle in conical space

- C. Filgueiras, F. Moraes
- Physics
- 9 September 2008

Abstract A quantum neutral particle, constrained to move on a conical surface, is used as a toy model to explore bound states due to both a inverse squared distance potential and a δ -function… Expand

Position-dependent mass effects in the electronic transport of two-dimensional quantum systems

- F. Serafim, F. Santos, J. Lima, C. Filgueiras, F. Moraes
- Physics
- 12 September 2018

In this work, we investigate the electronic transport properties of curved two-dimensional quantum systems with a position-dependent mass (PDM). We found the Schr\"odinger equation for a general… Expand

Landau levels, self-adjoint extensions and Hall conductivity on a cone

- A. Poux, L. Araújo, C. Filgueiras, F. Moraes
- Physics
- 26 May 2014

In this work we obtain the Landau levels and the Hall conductivity at zero temperature of a two-dimensional electron gas on a conical surface. We investigate the integer quantum Hall effect… Expand

On Aharonov?Casher scattering in a CPT-odd Lorentz-violating background

- F. M. Andrade, E. Silva, T. Prudêncio, C. Filgueiras
- Physics, Mathematics
- 7 March 2013

The effects of a Lorentz symmetry-violating background vector on Aharonov?Casher scattering in the nonrelativistic limit are considered. Using the self-adjoint extension method, we find that there is… Expand

On Aharonov–Casher bound states

- E. Silva, F. M. Andrade, C. Filgueiras, H. Belich
- Physics, Mathematics
- 14 March 2012

In this work bound states for the Aharonov–Casher problem are considered. According to Hagen’s work on the exact equivalence between spin-1/2 Aharonov–Bohm and Aharonov–Casher effects, is known that… Expand

The effect of singular potentials on the harmonic oscillator

- C. Filgueiras, E. Silva, W. Oliveira, F. Moraes
- Physics
- 1 November 2010

Abstract We address the problem of a quantum particle moving under interactions presenting singularities. The self-adjoint extension approach is used to guarantee that the Hamiltonian is self-adjoint… Expand
