The magnetic component of quark-gluon plasma is also a liquid

The magnetic scenario for strongly coupled quark-gluon plasma (sQGP) emphasizes the role of monopoles near or above the deconfinement temperature, and specifically predicts that they help reduce its viscosity by the "magnetic bottle" effect. Here we present results for monopole-(anti)monopole correlation functions from our classical molecular dynamics simulations, which are in good agreement with the lattice results. By analysis of the correlation functions, we show that the magnetic Coulomb coupling runs in the direction opposite to the electric one. However, as T decreases to Tc, the magnetic coupling never gets too weak, with the plasma parameter always large enough (Γ>1). This nicely agrees with empirical evidence from the BNL Relativistic Heavy Ion Collider experiments, implying that magnetic objects should also form a good liquid with low viscosity.
