Abstract

We study the electromagnetic conductivity of QGP in a magnetic background by lattice simulations with Nf=2+1 dynamical rooted 2-stout smeared staggered fermions at the physical point. We study the correlation functions of the electromagnetic currents at T=200, 250 MeV and use the Tikhonov approach t...
