Quarkyonic phase in holographic approach

Abstract: We consider the holographic models that are supported by the Einstein action with the dilaton field and Maxwell fields. The holographic model, arXiv:2203.12539, describes media with non-zero temperature, chemical potential, spatial anisotropy and external magnetic field, and reproduces the expected first order phase transition for light quarks. We determine the jumps near first order phase transition for string tension, baryonic density and electrical conductivity for the model. For some parameters of anisotropy and magnetic field we find the new phase with significantly smaller values of string tension, baryonic density and electrical conductivity, but this phase is still located in the confinement zone. This phase is located between the confinement/deconfinement phase transition line and first order phase transition line in (temperature, chemical potential) plane and can be interpreted as a quarkyonic phase.
