Fuzzy Ring from M2-brane Giant Torus

Understand

We construct spinning dual M2 giant gravitons in AdS_4 x S^7, which generically become 1/16 BPS states, and show that their world-volumes become torii.

• By taking an orbifold, we obtain spinning dielectric D2-brane configurations in AdS_4 x CP^3 dual to specific BPS operators in ABJM theory.
• This reveals a novel mechanism how to give an angular momentum to a dielectric D2-brane.
• We also find that when its angular momentum in the AdS_4 becomes large, it approaches to a ring-like object.
