HET Seminar | Oscar Varela, Utah State University | "AdS4/CFT3 Squashed, Stretched, Warped and Invaded" | via Zoom

The spectrum of single-trace operators of holographic CFTs at strong coupling and large N can be mapped to the spectrum of Kaluza-Klein modes over the dual AdS supergravity solutions. In this talk, I will focus on two specific CFT3s with AdS4xS7 gravity duals that arise as infrared fixed points of the ABJM M2-brane field theory deformed with a certain quadratic and a certain cubic superpotential. In both cases, the AdS4xS7 product is warped and the metric on S7 is squashed and stretched. In the quadratic case, I will show how Exceptional Field Theory techniques can be used to compute the entire spectrum. In the cubic case, I will show that the spectrum exhibits a space-invaders scenario, similar to that known to occur for another squashed AdS4xS7 solution.
