Non-Abelian Giant Gravitons

TL;DR

This paper proposes a microscopical description of giant graviton configurations using non-Abelian gravitational waves with dielectric effects, demonstrating stable solutions that match known configurations in the large N limit.

Contribution

It introduces a non-Abelian effective action for gravitational waves with dielectric couplings, providing a new microscopic perspective on giant gravitons.

Findings

Stable dielectric solutions exist for the proposed non-Abelian gravitational wave action.

Large N limit solutions agree with classical giant graviton configurations.

The work offers a complementary microscopical description of giant gravitons.

Abstract

We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a dielectric (or magnetic moment) effect. We present a non-Abelian effective action for these gravitational waves with dielectric couplings and show that stable dielectric solutions exist. These solutions agree in the large $N$ limit with the giant graviton configurations in the literature.
