Bosonic string with antisymmetric fields and a non-local Casimir effect

TL;DR

This paper explores a bosonic string theory coupled with antisymmetric fields, revealing a non-local Casimir effect through a Coulomb-like interaction derived from a zeta function approach.

Contribution

It introduces a novel non-standard coupling of bosonic strings with antisymmetric fields and interprets the resulting static potential as a non-local Casimir effect.

Findings

A Coulomb-like interaction term is generated by integrating out antisymmetric fields.

The static potential is derived from a non-local zeta function approximation.

The static potential is interpreted as a non-local Casimir effect.

Abstract

The coupling, in a non-standard way, of a bosonic string theory with a dilaton and antisymmetric fields is investigated. By integrating over the antisymmetric fields, a Coulomb-like interaction term is generated. The static potential of a theory of this kind is obtained from the corresponding non-local zeta function, in some approximation. An interpretation of the static potential as a type of non-local Casimir effect is given.
