DESCRIPTION:Speakers: Savvas Zafeiropoulos (Goethe University Frankfurt)\n
We study a Random Matrix Model for QCD at finite density via Complex Lange
vin dynamics. This model has a phase transition to a phase with non-zero b
aryon density. We study the convergence of the algorithm as a function of
the quark mass and the chemical potential and focus on two main observable
s: the baryon density and the chiral condensate. As expected\, for simulat
ions close to the chiral limit\, the algorithm has wrong convergence prope
rties when the quark mass is in the spectral domain of the quenched Dirac
operator. Possible solutions of this problem are discussed.\n\nhttps://co
