Gauge/Gravity Duality and Some Applications

Understand

We discuss the AdS/CFT correspondence in which space-time emerges from an interacting theory of D-branes and open strings.

• These ideas have a historical continuity with QCD which is an interacting theory of quarks and gluons.
• In particular we review the classic case of D3 branes and the non-conformal D1 brane system.
• We outline by some illustrative examples the calculations that are enabled in a strongly coupled gauge theory by correspondence with dynamical horizons in semi-classical gravity in one higher dimension.
