| Research Abstract |
We have studied the equation of state on the lattice. We apply the T-integration method to nonperturbatively calculate the equation of state by the fixed-scale approach. First we demonstrated our approach in the SU(3) gauge theory. Second, we study the equation of state in 2+1 flavor QCD with nonperturbatively improved Wilson quarks coupled with the RG-improved Iwasaki glue. Although the light quark masses are heavier than the physical values yet, our equation of state is roughly consistent with results with highly improved staggered quarks at large Nt. Third, we just started to generate finite temperature configuration on the physical point which has investigated by PACS-CS. The QCD common code, Bridge++, is adopted to generate the configurations on KEK BlueGene computers.
