Abstract
Abstract In our previous paper (Aref’eva et al. in JHEP 07:161, 2021, arXiv:2011.07023 [hep-th]) we have constructed a twice anisotropic five-dimensional holographic model supported by Einstein-dilaton-three-Maxwell action that reproduced some essential features of the “heavy quarks” model. However, that model did not describe the magnetic catalysis (MC) phenomena expected from lattice results for the QGP made up from heavy quarks. In this paper we fill this gap and construct the model that improves the previous one. It keeps typical properties of the heavy quarks phase diagram, and meanwhile possesses the MC. The deformation of previous model includes the modification of the “heavy quarks” warp factor and the coupling function for the Maxwell field providing the non-trivial chemical potential.
