AbstractAbstract
[en] We review the status of applications of the hybrid stochastic algorithm of S. Duane to lattice gauge theory with fermion feedback. We illustrate optimization of the algorithm and its application to calculate the chiral condensate in SU(2) and SU(3) gauge theories with four species of almost massless quarks. Studies of the thermodynamics of QCD indicate that fermion feedback eliminates the first order deconfining transition of the pure gluon theory when the quark mass is small (less than 1.3 Λms, roughly).
