Equation of state in (2+1)-flavor QCD at physical point with improved Wilson fermion action using gradient flow
We study the energy-momentum tensor and the equation of state as well as the
chiral condensate in (2+1)-flavor QCD at the physical point applying the method
of Makino and Suzuki based on the gradient flow. We adopt a nonperturbatively
O(a)-improved Wilson quark action and the renormalization group-improved
Iwasaki gauge action. At Lattice 2016, we have presented our preliminary
results of our study in (2+1)-flavor QCD at a heavy u, d quark mass point. We
now extend the study to the physical point and perform finite-temperature
simulations in the range T \simeq 155--544 MeV (Nt = 4--14 including odd Nt's)
at a \simeq 0.09 fm. We show our final results of the heavy QCD study and
present some preliminary results obtained at the physical point so far.Comment: 8 pages, 15 figures, talk presented at the 35th International
