We construct all supergravity theories that can be obtained through factorized projections of N = 8 supergravity, exposing their double-copy structure, and calculate their one-loop four-point scattering amplitudes. We derive representations of gluon...

Classical conformal blocks appear in the limit c->infinity of the Virasoro conformal blocks. Classical conformal blocks have close relationship to monodromy of the second order differential equations with regular singularities. I will discuss...

I will discuss how to compute Entanglement Renyi Entropies for two dimensional holographic CFTs using AdS_3 handlebody solutions. Some simplifying assumptions are made. The answer I find is consistent with the Ryu-Takayanagi prediction for...

The electron edm is an important constraint on extensions to the Standard Model such as supersymmetric models. ACME is closing in on a more sensitive measurement of this moment, profiting from the huge electric field within the ThO molecule.
