"Anderson transition in the spectrum of the Dirac operator
of Quantum Chromodynamics at high temperature"

We study the eigenmodes of the QCD Dirac operator at high temperature. We
that the lowest modes are statistically independent, obeying Poisson
however modes higher up in the spectrum are delocalized, obeying Random Matrix
statistics. In this talk we examine the nature of the transition between these
two types of eigenmodes in the spectrum and show our results for the
length critical exponent (nu) from two completely different types of
observables: eigenvalues and eigenvectors. The critical exponents computed
both observables was found to be compatible with each other and with the
available results for the 3D unitary Anderson model.
