Description
We explore the distribution of the energy momentum tensor (EMT) around quark—anti-quark and single quark at nonzero temperature in SU(3) Yang-Mills gauge theory. This is an extension of our previous study [1] on the EMT distribution in static quark—anti-quark systems in vacuum. We discuss the disappearance of the flux tube structure observed in the vacuum simulation. We investigate the total stress acting on the mid-plane between a quark and an anti-quark and show that it agrees with the force obtained from the derivative of the free energy. The color Debye screening effect in the deconfined phase is also discussed in terms of the EMT distribution.
