TL;DR

This paper explores the magnetic scenario of sQGP, showing a dense monopole plasma near the critical temperature that explains lattice potential energy and exhibits near-perfect liquid behavior with balanced electric and magnetic charges.

Contribution

It introduces a magnetic monopole plasma model for sQGP that explains potential energy and transport properties, aligning with experimental observations.

Findings

Dense monopole plasma supports flux tubes and explains potential energy.

Transport properties indicate a near-perfect liquid with balanced electric and magnetic charges.

Results align with the observed perfect liquid at RHIC.

Abstract

We describe recent developments of the "magnetic scenario" of sQGP. We show that at $T=(0.8-1.3)T_c$ there is a dense plasma of monopoles, capable of supporting metastable flux tubes. Their existence allows to quantitatively explained the non-trivial $T$-dependence of the static $\bar Q Q$ potential energy calculated on the lattice. By molecular dynamics simulation we derived transport properties (shear viscosity and diffusion constant) and showed that the best liquid is given by most symmetric plasma, with 50%-50% of electric and magnetic charges. The results are close to those of the ``perfect liquid'' observed at RHIC.
