We compare the eigenvalue spectra of the Dirac operator from a simulation with two mass degenerate dynamical chirally improved fermions with Random Matrix Theory. Comparisons with distributions of kth eigenvalues (k = 1, 2) in fixed topological sectors (nu = 0, 1) are carried out using the Kolmogorov-Smirnov test. The eigenvalue distributions are well described by the RMT predictions. The match allows us to read off the quark condensate in the chiral limit. Correcting for finite size and renormalization we obtain a mean value of -(276(11)(16) MeV)(3) in the (MS) over bar scheme. (c) 2007 Elsevier B.V. All rights reserved.
