The dynamics of heavy particles in a strongly coupled plasma is determined by transport coefficients. Especially for heavy quarkonia, the real-time evolution is described by transport coefficients $\kappa$ and $\gamma$.
On the lattice, these transport coefficients can be measured from correlators of chromoelectric fields connected by a Wilson line. Gradient flow is a beneficial tool to...
We measured the static force directly in the continuum limit on the lattice in quenched theory for the first time. A generalized Wilson loop with a chromoelectric field insertion in one of the temporal Wilson lines is the operator that measures the static force directly. However, chromoelectric field insertions converge slowly to the continuum and require an improvement. We use gradient flow...
