Description
The static forces between electric charges and currents are modified at the loop level by the presence of a plasma. While electric charges are screened, currents are not. This can be understood as medium-induced ‘antiscreening’ of the Ampere force and enters the constitutive equation of the electric current at second order in a ‘hydrodynamic’ description as the quantity $\kappa_t$. We investigate these effects and this second order ’hydro-coefficient’ quantitatively using non-perturbative simulations of QCD with two light degenerate flavors of quarks.
