"Random matrix theory and its applications to the strong interactions"


Abstract

In this talk I review how the concept of Random Matrix Theory (RMT) is 
used as an effective field theory of the theory of strong interactions 
in Quantum Chromodynamics (QCD).  I begin by stating the approximations 
made that map QCD to a sigma model - the theory of Goldstone modes - and 
ultimately to a RMT formulation. Various correlation functions in the 
relevant symmetry class can be computed either from the sigma model or 
RMT, and then compared to numerical solutions of QCD in that limiting 
regime.  Recent developments include non-Hermitian RMT and complex 
eigenvalue spectra of the QCD Dirac operator.
