Landau Quantization of Neutral Particles in an External Field
Claudio Furtado, J. R. Nascimento, L. R. Ribeiro
The quantum dynamics of an induced electric dipole in the presence of a configuration of crossed electric and magnetic fields is analyzed. This field configuration confines the dip…
Aharonov-Bohm Effect on Noncommutative Plane: A Coherent State Approach
M. A. Anacleto, J. R. Nascimento, A. Yu. Petrov
We apply the coherent state approach to study Aharonov-Bohm effect in the field theory context. We verify that, contrarily to the commutative result, the scattering amplitude is ul…
A Remark on Lorentz Violation at Finite Temperature
F. A. Brito, T. Mariz, J. R. Nascimento +2
We investigate the radiatively induced Chern-Simons-like term in four-dimensional field theory at finite temperature. The Chern-Simons-like term is temperature dependent and breaks…
Landau Levels Analog to Electric Dipole
L. R. Ribeiro, Claudio Furtado, J. R. Nascimento
In this letter we study the quantum dyamics of a neutral particle in the presence of an external magnetic field. We demonstrate in a specific field-dipole configuration that we hav…
