Abstract
A novel method to study the bulk thermodynamics in lattice gauge theory is proposed on the basis of the Yang-Mills gradient flow with a fictitious time t. The energy density and the pressure P of SU(3) gauge theory at fixed temperature are calculated directly on 323×(6,8,10) lattices from the thermal average of the well-defined energy-momentum tensor TμνR(x) obtained by the gradient flow. It is demonstrated that the continuum limit can be taken in a controlled manner from the t dependence of the flowed data.
