Simulating Lattice QCD at Finite Baryon Density
Philippe de Forcrand, ETH & KITP

At non-zero baryon density, simulations of lattice QCD face a "sign problem" which prevents significant progress. In particular, the phase diagram of QCD as a function of temperature and chemical potential remains largely unknown. I recall the nature of the sign problem, the approaches used to circumvent it at small density, and point to a possible direction for progress.
