Phase Diagram Magnetic Features of Holographic Anisotropic Model for $z^4$-term Heavy Quarks

Abstract

Thermodynamical features depending on magnetic field of the previously found five-dimensional anisotropic holographic solution for heavy quarks supported by Einstein-dilaton-three-Maxwell action with extended warp factor and improved coupling function for the Maxwell field providing chemical potential are studied. Direct/inverse magnetic catalysis behavior is considered. Phase diagram, composed of the 1-st order phase transition and temporal Wilson loops, corresponding to the stable direct magnetic catalysis scenario is presented. String tension behavior in magnetic field is discussed.
