# Chamblin Colloquium: String Theory and Strong Interactions

String theory was originally invented to describe hadrons, but soon after Quantum Chromodynamics (QCD) emerged as the precise theory of the strong nuclear force. A quarter century later it was understood that string theory and certain gauge theories akin to QCD are in fact different descriptions of the same physics. I will review the basic relations between gauge theories and strings, and will motivate the exact gauge/string dualities by studying coincident D-branes. I will also discuss applications of these ideas to theories at finite temperature and to gauge theories which exhibit color confinement. The colloquium will also cover some of the recent progress, including the quantum entanglement entropy and three-dimensional conformal field theory.

This is the 2016 Chamblin Colloquium, in memory of our colleague Andrew Chamblin of the University of Louisville. There will be a special reception beginning at 3pm in CP179.
