  In this article the anomalous dimension of a class of operators with a bare
dimension of O(N) is studied. The operators considered are dual to excited
states of a two giant graviton system. In the Yang Mills theory they are
described by restricted Schur polynomials, labeled with Young diagrams that
have at most two columns. In a certain limit the dilatation operator looks like
a lattice version of a second derivative, with the lattice emerging from the
Young diagram itself.
