Description
One of the important missions of high energy heavy ion collisions is to reveal the QCD phase structure at finite temperature and baryon density. Lattice QCD simulations are expected to provide valuable information as a first principle calculation of QCD. However, lattice simulations at finite baryon density have suffered from the sign problem' and no calculations were successful except at very low density. FEFU group has developed a method,Canonical Approach', for beating the sign problem. This method was known, but not practical. We have studied origins of errors and instability, and now we are near to the final goal.
