Giant Gravitons from Holomorphic Surfaces

TL;DR

This paper introduces a new class of supersymmetric cycles in AdS and related spacetimes, generalizing giant gravitons, which preserve varying fractions of supersymmetry and correspond to superpositions of BPS states in the dual CFT.

Contribution

It presents a novel construction of supersymmetric cycles in AdS and $T^{1,1}$ spaces, extending the concept of giant gravitons and analyzing their supersymmetry properties.

Findings

Branes wrapped on these cycles preserve 1/2, 1/4, or 1/8 of supersymmetry.

Configurations correspond to superpositions of BPS states in the dual CFT.

Generalizes known giant graviton solutions to new supersymmetric cycles.

Abstract

We introduce a class of supersymmetric cycles in spacetimes of the form AdS times a sphere or $T^{1,1}$ which can be considered as generalizations of the giant gravitons. Branes wrapped on these cycles preserve $1\over 2$, $1\over 4$ or $1\over 8$ of the supersymmetry. On the CFT side these configurations correspond to superpositions of the large number of BPS states.
