Description

We present our 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 chemical potential and the
Backus-Gilbert method is used to extract the conductivity from
current-current correlators. Our preliminary results show
an increase of conductivity with real baryon density.
