Description
We propose a novel method to define and calculate the
energy-momentum tensor (EMT) in lattice gauge theory on the basis of the
Yang-Mills gradient flow.
Using this method, we measure the thermodynamics of SU(3) gauge theoy on
fine
lattices with lattice size up to 64^3x18.
The numerical results with small lattice spacing confirm our previous
findings;
the expectation values of the EMT have reasonable dependences on the flow
time
near the continuum limit, and thus our method can successfully be applied
to the
analysis of the EMT on the lattice.
