Holography and Regge Phases with large U(1) Charge
Wei Li, Boston University,

We use holography to study the large spin J limit of the spectrum of lowest-twist states with charge Q under a U(1) conserved current in CFTs in d > 2 dimensions, with a focus on d=3 and d=4. We study in detail the holographic description of such states at Q > 2, by considering the contribution to the energies of Q scalar particles coming from single photon and graviton exchange in the bulk of AdS. For a range of finite values of Q and J, we numerically diagonalize the Hamiltonian for such states and examine the resulting spectrum and wavefunctions. We discuss the extension of these results to the regime of parametrically large charge Q, as well as to what extent such results are expected to hold universally, beyond the limit of holographic CFTs. At last we compare our holographic computations to numerical bootstrap data for the 3d O(2) CFT data at Q=3 and Q=4.

The talk is in 469 Lauritsen.
