Bound states in the dynamics of a dipole in the presence of a conical defect
C. A. de Lima Ribeiro, Claudio Furtado, Fernando Moraes
In this work we investigate the quantum dynamics of an electric dipole in a -dimensional conical spacetime. For specific conditions, the Schrödinger equation is solved and b…

Quantum Dynamics of Magnetic and Electric Dipoles and Berry's Phase
Claudio Furtado, C. A. de Lima Ribeiro
We study the quantum dynamics of neutral particle that posseses a permanent magnetic and electric dipole moments in the presence of an electromagnetic field. The analysis of this d…

Solid State Analog for He-McKellar-Wilkens Quantum Phase
C. A. de Lima Ribeiro, Claudio Furtado, Fernando Moraes
In this letter we investigate the quantum dynamics of a quasiparticle in the presence of a charged screw dislocation submitted to a uniform magnetic field. Analysing the quantum sc…
