Description

In this report we present the results on the study of the electromagnetic conductivity in dense quark-gluon
plasma obtained within lattice simulations with Nf=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 current-current correlators. Our results indicate
an increase of QGP electromagnetic conductivity with real baryon density, and this dependence is quite strong.
