摘要:I describe a recent calculation (by me, Hoffmann, Liu, and Schaefer) of the chiral condensate in
one-flavor QCD using numerical simulations with overlap fermions. The condensate is extracted
by fitting the distribution of low lying eigenmodes of the Dirac operator in sectors of fixed topological
charge to the predictions of Random Matrix Theory. Our results are in excellent agreement
with estimates from the orientifold large-N expansion. Much interesting physics surrounds this
calculation, which I will highlight.
