Charged brane interactions via the Kalb-Ramond field

Abstract

Due to its versatility, the 2-form field has been employed to describe a multitude of scenarios that range from high energy to condensed matter physics. Pushing forward in this endeavor we study the interaction energy, intermediated by this kind of field, between branes in a variety of configurations. Also the so-called Cremmer-Scherk-Kalb-Ramond model, which consists of the electromagnetic field coupled to the Kalb-Ramond gauge potential, is considered. It turns out that these models exhibit a much richer class of sources than usually thought, able to intermediate novel forms of interactions in different scenarios.

Field theoretic description of partially reflective surfaces

“…Moreover, since δ-like external sources can describe charges and mulipole distributions along branes of arbitrary dimensions in several different scenarios [18,20,21], we hope that the model presented here can advance the endeavor of better understanding some interesting physical signatures. Not only about the long-standing issue of atoms in interaction with different kinds of surfaces but also regarding the interaction between dissimilar surfaces and multilayered materials (see for instance [23]).…”

Simple prescription for computing the nonrelativistic interparticle potential energy related to dual models

“…[5], we consider external currents concentrated along two parallel d-dimensional branes (d ≤ 2). The case d = 0 leads to the usual point-like distributions.…”

An Alternative Approach to the Electric Charge Quantization with Non-global Potentials

“…In previous papers, we have proposed an alternative approach, a variant of the Wu-Yang treatment, to justify the electric charge quantization by means of non-global potentials [30,31]. Although relying on the Wu-Yang potential (2), we have interpreted it as a pure non-global gauge field, in the sense that it was not defined all over a given region of space, an infinite line, that is.…”

“…, specially those concerning fiber bundles [22][23][24][25], the use of non-divergent potentials [26,27], classical theory of dyons [28,29], charge quantization without magnetic monopoles [30,31], and charge quantization in the context of the standard model [32][33][34][35][36].…”

“…In this interpretation, the factor g on the right-hand side of (2) is a simple gauge parameter, not a monopole intensity. Introduced in connection with the Aharonov-Bohm effect [30], this procedure was subsequently used as a pure gauge transformation [31].…”
