Gravitating tensor monopole in a Lorentz-violating field theory

TL;DR

This paper introduces a solution involving a tensor monopole in a Lorentz-violating field theory, highlighting its unique observational signatures that could help distinguish it from scalar monopoles in astrophysical data.

Contribution

It provides a novel solution to Einstein and tensor field equations with Lorentz symmetry breaking and discusses potential observational signatures.

Findings

Tensor monopoles exhibit distinct deflection angles from scalar monopoles.

Detection of monopoles could reveal Lorentz symmetry violation.

The study suggests new astrophysical avenues to test Lorentz violation.

Abstract

We present a solution of the coupled Einstein and rank-two antisymmetric tensor field equations where Lorentz symmetry is spontaneously broken, and we discuss its observational signatures. Especially, the deflection angles have important qualitative differences between tensor and scalar monopoles. If a monopole were to be detected, it would be discriminated whether or not to correspond to a tensor one. This phenomenon might open up new direction in the search of Lorentz violation with future astrophysical observations.
