Localization of scalar and tensor fields in the standing wave braneworld with increasing warp factor

TL;DR

This paper studies how scalar and tensor fields can be localized on a brane in a 5D spacetime with standing gravitational waves, demonstrating the existence of normalizable zero modes even with an increasing warp factor.

Contribution

It shows that scalar and tensor fields can be localized on a brane with an increasing warp factor, expanding understanding of field localization in braneworld models.

Findings

Normalizable zero modes exist for scalar and tensor fields

Localization occurs despite increasing warp factor

Supports viability of standing wave braneworld scenarios

Abstract

We investigate scalar and tensor fields in the brane model solution for the 5D space-time with standing gravitational waves in the bulk and show that even in the case of increasing warp factor there exist normalizable zero modes localized on the brane.
