| Outline of Final Research Achievements |
We investigate thermodynamic properties of quark matter by a systematic study of finite temperature QCD with (2+1) flavors of improved Wilson quarks applying the Suzuki method based on the gradient flow. As the first step, we studied the case of heavy u and d quarks on a fine lattice. We found that the the energy-momentum tensor is consistent with our previous evaluation of the equation of state adopting a conventional method, and that the chiral condensate and the chiral susceptibility show a clear signal of chiral restoration at pseudocritical temperature suggested by previous observations. We also find that the results of the gluonic definition for the topological susceptibility are consistent with those of the fermionic definition already on finite lattices. Extending the study to QCD with physical u and d quarks, we got preliminary results suggesting the transition temperature consistent with previous studies with staggered-type quarks. We also studied viscosities etc.
