Query: Quark localization in QCD above $T_c$   It was previously found that at high temperature the lowest part of the QCD
Dirac spectrum consists of localized modes obeying Poisson statistics. Higher
up in the spectrum, modes become delocalized and their statistics can be
described by random matrix theory. The transition from localized to delocalized
modes is analogous to the Anderson metal-insulator transition. Here we use
dynamical QCD simulations with staggered quarks to study this localization
phenomenon. We show that the "mobility edge", separating localized and
delocalized modes, scales properly in the continuum limit and rises steeply
with the temperature. Using very high statistics simulations in large volumes
we find that the density of localized modes scales precisely with the spatial
volume and even at $T=2.6T_{c}$ the lowest part of the spectrum extends all the
way down to zero with no evidence of a spectral gap.
