Outline of Final Research Achievements |
We studied quantum chromodynamics (QCD) at high temperature and density by numerical simulations. Treating the quark masses as parameters of the system as well as the temperature and chemical potential, we investigated the nature of phase transitions by calculating probability distribution functions. We investigated the critical surface which separates the first order transition and crossover regions in the heavy quark region, and demonstrated the usefulness of our method. The pressure gap and the latent heat between the two phases at the first phase transition were calculated when the quark mass is infinite. Furthermore, we tried calculation of thermodynamic quantities using the gradient flow method which has recently attracted attention.
