Abstract :We study thermodynamics of SU(3) gauge theory at xed scales on the lattice, where we vary temperature by changing the temporal lattice size Nt =(Tat )􀀀1. 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.
