Description
In this talk we begin by introducing Spin Matrix theory
(SMT). It can be seen as a finite-N generalization of a
nearest neighbor spin chain. SMT describes N=4 SYM near
certain unitarity bounds and zero-temperature critical points.
We find a new tractable regime at finite N described by a
classical matrix model. Next we go to the string side of the
AdS/CFT correspondence and explain that the dual is given
by highly excited giant gravitons. Finally, we match the
matrix model to interacting giant gravitons on AdS using the
non-abelian DBI action.
