Abstract: Quantum field theory is a unified language that successfully describes many diverse phenomena in different areas of physics. Nevertheless many interesting theories that arise in nature remain poorly understood, in part because there are no general tools for analyzing them in the strong coupling regime. In this talk I will review some recent progress in developing such tools, focusing … Read More

Abstract: I will describe several different ways of thinking about the AdS/CFT correspondence. In particular I’ll discuss how locality in d+1 spacetime dimensions can arise from a d-dimensional theory. I will also highlight major open problems, including the black hole information paradox, and strategies that may lead to its resolution.
