In the xed scale approach, nite temperature simulations are performed on common lattice spacings and spatial volumes. Consequently, we can isolate thermal effects in observables from other uncertainties, such as lattice artifact, renormalization factor, and spatial volume effect. Furthermore, in the EOS calculations, the xed scale approach is able to reduce computational costs for zero temperature subtraction and parameter search to nd lines of constant physics, which are demanding in full QCD simulations. As a test of the approach, we study the thermodynamics of the SU(3) gauge theory on isotropic and anisotropic lattices. In addition to the equation of state, we calculate the critical temperature and the static quark free energy at a xed scale.The XXVI Internaitonal Symposium on Lattice Field Theory July 14-19 2008 Williamsburg, Virginia, USASISSA2008-07engconference paperhttp://hdl.handle.net/10191/27698https://niigata-u.repo.nii.ac.jp/records/3100218248039PoS - Proceedings of SciencePoS - Proceedings of ScienceLattice200817417https://niigata-u.repo.nii.ac.jp/record/31002/files/LATTICE 2008_174.pdfapplication/pdf317.8 kB2019-08-26
