A comment on bouncing and cyclic branes in more than one extra-dimension

TL;DR

This paper discusses how bouncing branes naturally occur in higher-dimensional spaces with multiple extra dimensions, especially when branes have sufficient angular momentum, preventing them from reaching horizons.

Contribution

It introduces the concept that multiple extra dimensions lead to bouncing branes, with detailed analysis in specific backgrounds like AdS_5-Schwarzschild-S_5.

Findings

Bouncing branes occur naturally in spaces with more than one extra dimension.

High angular momentum creates a repulsive barrier preventing branes from reaching horizons.

The phenomenon is illustrated with D3-branes in specific spacetime backgrounds.

Abstract

We argue that bouncing branes occur naturally when there is more than one extra-dimension. We consider three-branes embedded in space-times with a horizon and an isometry group SO(6). As soon as the brane angular momentum is large enough, a repulsive barrier prevents the branes from reaching the horizon. We illustrate this phenomenon with the case of D3-branes in an AdS_5-Schwarzschild-S_5 background and asymptotically flat space-time.
