2+1 flavor QCD with the fixed point action in the $ε$ -regime

arXiv:0710.0551

Abstract

We generated configurations with the approximate fixed-point Dirac operator $D_{FP}$ on a $1 2^{4}$ lattice with $a \approx 0.13$ fm where the scale was set by $r_{0}$ . The distributions of the low lying eigenvalues in different topological sectors were compared with those of the Random Matrix Theory which leads to a prediction of the chiral condensate.
