Electromagnetic conductivity of quark-gluon plasma at non-zero baryon density
May 16, 2022
In this preprint we present our results on the study of the electromagnetic conductivity in dense quark-gluon plasma obtained within lattice simulations with $N_f = 2 + 1$ dynamical quarks. We employ stout improved rooted staggered quarks at the physical
point and the tree-level Symanzik improved gauge action.
The simulations are performed at imaginary baryon chemical potential, and the
Tikhonov regularisation method is used to extract the conductivity from
Our results indicate
an increase of QGP electromagnetic conductivity with real baryon density, and this dependence is quite strong.
