From weak to strong coupling in ABJM theory

Drukker, Nadav, Marino, Marcos, Putrov, Pavel

Understand

The partition function of N=6 supersymmetric Chern-Simons-matter theory (known as ABJM theory) on S^3, as well as certain Wilson loop observables, are captured by a zero dimensional super-matrix model.

  • This super-matrix model is closely related to a matrix model describing topological Chern-Simons theory on a lens space.
  • We explore further these recent observations and extract more exact results in ABJM theory from the matrix model.
  • In particular we calculate the planar free energy, which matches at strong coupling the classical IIA supergravity action on AdS_4 x CP^3 and gives the correct N^{3/2} scaling for the number of degrees of freedom of the M2 brane theory.
