Dynamical Domain Wall and Localization

TL;DR

This paper explores how various fields, including chiral spinors, can be localized on a dynamical domain wall in five-dimensional space-time, contributing to models of our universe within higher-dimensional theories.

Contribution

It demonstrates the successful localization of chiral spinors on a dynamical domain wall, advancing previous models by addressing a key challenge in field localization.

Findings

Chiral spinors can be localized on the dynamical domain wall.

The four-dimensional FRW universe can be realized on the domain wall.

The work extends previous models by achieving spinor localization.

Abstract

Based on the previous works (arXiv:1202.5375 and 1402.1346), we investigate the localization of the fields on the dynamical domain wall, where the four dimensional FRW universe is realized on the domain wall in the five dimensional space-time. Especially we show that the chiral spinor can localize on the domain wall, which has not been succeeded in the past works as the seminal work in arXiv:0810.3746.
