We construct solutions of IIB supergravity dual to non-supersymmetric states of the D1D5 system. These solutions are constructed as perturbations carrying both left and right moving momentum around the maximally rotating D1D5 ground state at linear order. They are found by extending to the asymptotically flat region the geometry gener- ated in...

We derive an explicit expression for the 1/c con- tribution to the Virasoro blocks in 2D CFT in the limit of large c with fixed values of the operators' dimensions. We follow the direct approach of orthonormalising, at order 1/c, the space of the Virasoro descendants to obtain the blocks as a series expansion around z = 0. For generic conformal...
