Direct photons emission rate and electric conductivity in fully anisotropic QGP holographic model with first order phase transition


Abstract in English

The electric conductivity is considered in the fully anisotropic holographic theory. The electric conductivity is derived in two different ways, and their equivalence for the fully anisotropic theory is shown. Numerical calculations of the electric conductivity were done for Einstein-dilaton-three-Maxwell holographic model [29]. The dependence of the conductivity on the temperature, the chemical potential, the external magnetic field, and the spatial anisotropy of the heavy-ions collision (HIC) is studied. The electric conductivity jumps near the first-order phase transition are observed. This effect is similar to the jumps of holographic entanglement that were studied previously.
