Abstract:
Anisotropic holographic models of quantum chromodynamics will be discussed. Within the framework of these models, the structure of phase transitions of the Hawking-Page type and transitions associated with the behavior of Wilson loops, as well as other phenomena associated with anisotropy at nonzero temperature, chemical potential, and magnetic field, has been studied. The considered holographic models are supported by the Einstein action with the dilaton field and Maxwell fields. Maxwell's first field is connected with the introduction of the chemical potential. The second field is characterized by the parameter $\nu$ and provides spatial anisotropy in collisions of heavy ions, and at $\nu=4.5$ it makes it possible to reproduce the experimental energy dependence of the multiplicity of produced particles. The third field describes the anisotropy associated with an external magnetic field.
