Title QCD energy momentum tensor on lattice using gradient flow
Abstract Energy-momentum tensor is a basic quantity in the field theory related to the translation invariance. Nevertheless it is difficult to define it on lattice as a universal quantity. I order to solve the problem we apply the gradient flow method to Nf=2+1 full QCD at finite temperature. Our main interest is the following:
(1). Definition of the energy-momentum tensor on lattice.
(2). Calculation of thermodynamical quantities; the pressure, the energy density, the entropy density, the trace anomaly as a diagonal part of the energy-momentum tensor.
(3). Correlation function of the energy-momentum tensor and its physical highlights.
(4). Chiral condensate and its susceptibility with the Wilson fermion.
