AB  - We study the impact of self-generated electromagnetic fields (EMF) on   the momentum evolution of charm quarks in the partonic and hadronic   medium created in heavy-ion collisions at energies available at the   Relativistic Heavy Ion Collier (RHIC), using the parton-hadron-string   dynamics (PHSD) off-shell transport approach. In the quark-gluon plasma   (QGP) phase, the charm quark interacts with the off-shell partons, whose   mass and widths are given by the dynamical quasiparticle model (DQPM),   which can reproduce the lattice QCD thermodynamics. The background   electromagnetic fields are computed dynamically within the PHSD   considering both the spectators and participants protons as well as   newly produced charged hadrons, quarks, and antiquarks, which reflects   naturally the electric conductivity sigma el of the medium. We study the   directed and elliptic flow of D mesons in the presence of   electromagnetic fields. We find that electromagnetically induced v1   splitting in the D meson through D0 and D0 mesons is consistent with the   experimental data. Furthermore, we notice that the v1 splitting in the   heavy quark as a function of pT is more prominent as a probe of the   produced electromagnetic fields. However, we find only a small impact of   electromagnetic fields on the heavy quark elliptic flow v2.
