# Dynamics of domain wall in charged AdS dilaton black hole spacetime

## TL;DR

This paper investigates the dynamics of a domain wall universe induced by a charged dilaton black hole in AdS space, revealing unique expansion/collapse behavior and an unexplained anomaly outside the horizon.

## Contribution

It introduces a new analysis of domain wall motion in charged dilaton black hole backgrounds, highlighting an unexpected motion area outside the horizon.

## Key findings

- Domain wall exhibits expansion or collapse behavior.
- Existence of an anomalous motion area outside the horizon.
- Single cosmological behavior in static AdS space.

## Abstract

For the $n-1$ dimensional FRW domain wall universe induced by $n$ dimensional charged dilaton black hole, its movement formula in the bulk can be rewrite as the expansion or collapsing of domain wall. By analysing, we found that in this static AdS space, the cosmologic behaviour of domain wall is particularly single. Even more surprising, it exists an anomaly that the domain wall has a motion area outside of horizon, in which it cannot be explained by our classical theory.
