DESCRIPTION:Speakers: Savvas Zafeiropoulos (Goethe University of Frankfurt
)\nWe study a Random Matrix Model for QCD at finite density via Complex La
ngevin dynamics. This model has a phase transition to a phase with non-zer
o baryon density. We study the convergence of the algorithm as a function
of the quark mass and the chemical potential and focus on two main observa
bles: the baryon density and the chiral condensate. As expected\, for simu
lations close to the chiral limit\, the algorithm has wrong convergence pr
operties when the quark mass is in the spectral domain of the quenched Dir
ac operator. Possible solutions of this problem are discussed.\n\nhttps:/
