Description
We study the conductivity of quark-gluon matter in the presence of external magnetic field $B$ within LQCD with dynamical staggered $2 + 1$ quarks at physical pion $m_{\pi}$ and strange quark $m_s$ masses in the deconfinement phase $T = 200\,\mbox{MeV}$. We first measure the current-current Euclidean correlator, then extract the conductivity via analytical continuation within the Backus-Gilbert method. We observe that $\sigma_{\parallel}$ rapidly grows in the direction of magnetic field and that $\sigma_{\perp}$ on contrary decreases. This observation is in agreement with the Chiral Magnetic Effect (CME) predictions.
