Title: 3D supergravity & properties of 2D SCFTs

Speaker: Dr. Eoin O Colgain  (C. N. Yang Institute, SUNY Stony Brook)

Time: 2:30PM, July 23rd (Thursday)

Place: Theoretical Physics Division319

Abstract: 2D conformal field theories with N = (0,2) supersymmetry can be engineered by twisted compactifications of 4D N=4 super-Yang-Mills and 6D N = (2,0) theories on Riemann surface. We will review the construction of these CFTs and the determination of exact central charges and R symmetries via c-extremization. Using holography, we recast the trial central charge in terms of the superpotential of the corresponding 3D gauged supergravity. We discuss examples of 3D gravity theories and present all the supersymmetric solutions in closed form. Time permitting, we will comment on the fate of CFT data in gravity.
