Hints of Integrability Beyond the Planar Limit. (arXiv:0911.0967v1 [hep-th])

The problem of computing the anomalous dimensions of a class of (nearly)half-BPS operators with a large R-charge is reduced to the problem ofdiagonalizing a Cuntz oscillator chain. Due to the large dimension of theoperators we consider, non-planar corrections must be » Full text »
