The BPS spectrum of monopole operators in ABJM: towards a field theory description of the giant torus

Understand

We study the BPS spectrum of monopole operators in ABJM theory.

• First we work out the complete spectrum of the chiral ring by using a semiclassical analysis of the field theory compactified on a two sphere.
• By properly taking into account the full quantization condition of monopole charges, we show that the moduli space of ABJM theory with Chern-Simons level k, -k is a particular Z_k cover of the symmetric product of C^4/Z_k.
• We also work out in detail the spectrum of fluctuations around half-BPS monopole configurations and we find candidate states for a dual BPS configuration to the giant torus solution found by Nishioka and Takayanagi in the supergravity limit.
