Progress in complex Langevin simulations of full QCD at nonzero density

Understand

Progress in the application of the complex Langevin method to full QCD at non-zero chemical potential is reported.

• 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.
