“…The interaction between electric and magnetic fields and multipole moments has attracted attention in a great deal of studies, such as [1][2][3][4][5][6][7][8][9][10][11][12][13], the holonomic quantum computation [14][15][16], and the Landau quantization [17,18]. Besides, recent studies of the interaction between a moving electric moment and external fields [11,12] have shown a difference between the field configuration that yields the occurrence of geometric phases for an electric charge [1,2,19], an electric dipole moment [3,4,9,10], and a moving electric moment.…”

In this paper, we study the covariant form of the non-relativistic Schrödinger-Pauli equation in the spacetime generated by a cosmic string and discuss the solutions of this equation in the presence of interaction between the magnetic dipole momentum and electromagnetic field. We study the influence of the topology on this system. We obtain the solution of radial part as well as the energy levels. We consider all thermodynamic properties of a neutral particle in a magnetic cosmic string background by using an approach based on the partition function method.

“…To define the field configurations in this background, we suggest that the dipole moments are parallel to the z-axis again and that the electric field is outside of the defect. Thus, the electric field satisfying the conditions pointed out in the reference [15] is given by the expression (10), with the Aharonov-Casher uniform magnetic field is given by (12). In this case, the Schrödinger-Pauli equation in the presence of the torsion field takes the form…”

“…The dual of Aharonov-Casher effect was studied independently by He and McKellar [10] and Wilkens [11], who demonstrated that the quantum dynamics of the electric dipole in the presence of a magnetic field exhibits a geometrical quantum phase. In fact, the dynamics of dipoles can give rise to a variety of interesting physical effects [12,13,14]. Ericsson and Sjöqvist developed an analog of Landau quantization for neutral particles in the presence of an external electric field [15].…”

Landau quantization for a neutral particle in the presence of topological defects

In this paper we study the Landau levels in the non-relativistic dynamics of a neutral particle which possesses a permanent magnetic dipole moment interacting with an external electric field in the curved spacetime background with the presence or absence of a torsion field. The eigenfunction and eigenvalues of Hamiltonian are obtained. We show that the presence of the topological defect breaks the infinite degeneracy of the Landau levels arising in this system. We also apply a duality transformation to discuss this same quantization for a dynamics of a neutral particle with a permanent electric dipole moment. * Electronic address: kbakke,lrr,jroberto,furtado@fisica.ufpb.br

“…For instance, as a quite surprising case let us mention that, under certain circumstances, neutral particles with magnetic moment can exhibit the Aharonov-Bohm effect [52]. A quantum effect of the Aharonov-Bohm type for particles with an electric dipole appears, as a consequence of the relation between the topological properties of the phase shift and the linear and angular momentum of the electromagnetic field [53]. This topic is spiced with a hot debate about the force that a neutron experiences in connection with the Aharonov-Casher effect.…”

The limitations and possibilities that the concept of quantum interference offers as a tool for testing fundamental physics are explored here. The use of neutron interference as an instrument to confront against measurement readouts some of the principles behind metric theories of gravity will be analyzed, as well as some discrepancies between theory and experiment. The main restrictions that this model embodies for the study of some of the features of the structure of space-time will be explicitly pointed out. For instance, the conditions imposed by the necessary use of the semiclassical approximation. Additionally, the role that photon interference could play as an element in this context is also considered. In this realm we explore the differences between first-order and secondorder coherence experiments, and underline the fact that the Hanbury-Brown-Twiss effect could open up some interesting experimental possibilities in the analysis of the structure of space-time.The void, in connection with the description of wave phenomena, implicit in the principles of metric theories is analyzed. The conceptual difficulties, that this void entails, are commented.
