Title:
A Modified Probe Limit And A New Window Into Holography Defect CFTs
Speaker:
Abstract:
Brane intersections have long been the bread and but ter of holography. In addition to shedding light on strongly coupled defect- and boundary-CFTS, these models lie at the core of many holo graphic QCD and CMT models. Here I describe a modified version of the so-called probe approximation for a broad class of non-abelian supersymmetric brane intersections in the holographic limit, where the open strings on the probe Dq branes not only decouple, they are well-described by a tree-level Yang-Mills theory in curved space. This regime is particularly useful for studying these systems’ intricate vac uum structure, which I describe for several types of intersections, and localized finite-energy soliton states, which I will touch on briefly for the special case of D3/D5 intersections.
