Maths HEP Lunchtime Seminars: Matrix Models and QCD with Chemical Potential

Presented by Gernot Akemann, Brunel U.

2 March 2007 13:00 in CM221

The Random Matrix Model approach to Quantum Chromodynamics
with non-vanishing chemical potential is reviewed. The general concept
using global symmetries is introduced, as well as its relation to field
theory, the so-called epsilon regime of chiral Perturbation
Theory (echPT). Two types of Matrix Model results are distinguished:
phenomenological applications leading to phase diagrams, and an exact
limit of the QCD Dirac operator spectrum matching with echPT. All
known analytic results for the spectrum of complex and symplectic Matrix
Models with chemical potential are summarised for the symmetry classes of
ordinary and adjoint QCD, respectively. Comparisons of these predictions
to recent Lattice simulations are also discussed.
