Description
The complex Langevin method is extended to full QCD at non-zero
chemical potential. The method evades the sign problem which
makes naive simulations at nonzero density impossible.
The procedure 'gauge cooling' is used to stabilize the simulations
at small enough lattice spacings.
The method allows simulations also at high densities, all the way up
to saturation. The method is validated in the small chemical potential
region, where the sign problem is mild, and the reweighting approach is also feasible.
