Description
We study the temporal correlators of energy-momentum tensor in various channels in SU(3) gauge theory for two values of temperature T = 1.68T c and 2.24T c on the lattice. The correlators are measured using energy-momentum tensor operators constructed with the gradient flow, which is found to be quite effective to reduce the statistical error. We numerically confirm that temporal correlators including a conserved charge (energy or momentum) are constants as is consistent with the energy-momentum conservation. It is also checked that these constants satisfy the linear response relations. A novel measurement of specific heat from the energy-energy correlator is performed.
