1307.7748 (Denes Sexty)

Simulating full QCD at nonzero density using the complex Langevin

Denes Sexty
The complex Langevin method is extended to full QCD at non-zero chemical potential. The use of gauge cooling stabilizes the simulations for smooth lattices. At large fermion mass the results are compared to HQCD limit, where the spatial hoppings are neglected, and good agreement is found. The method allows simulations also at high densities, all the way up to saturation.
