Non-perturbative volume-reduction of large-N QCD with adjoint fermions

Understand

We use nonperturbative lattice techniques to study the volume-reduced "Eguchi-Kawai" version of four-dimensional large-N QCD with a single adjoint Dirac fermion.

• We explore the phase diagram of this single-site theory in the space of quark mass and gauge coupling using Wilson fermions for a number of colors in the range 8 <= N <= 15.
• Our evidence suggests that these values of N are large enough to determine the nature of the phase diagram for N-->oo.
• We identify the region in the parameter space where the (Z_N)^4 center-symmetry is intact.
