Dense quark–gluon plasma in strong magnetic fields
Abstract A non-perturbative (np) method of Field correlators (FCM) was applied to study QCD at temperatures above the deconfinement transition ($$1<T/T_c<3,~T_c\sim 0.16~\mathrm{GeV}$$ 1<T/Tc<3,Tc∼0.16GeV ) and nonzero baryon densities (baryon chemical potential $$\mu _B<0.5~\mathrm{G...

| description | Abstract A non-perturbative (np) method of Field correlators (FCM) was applied to study QCD at temperatures above the deconfinement transition ($$1<T/T_c<3,~T_c\sim 0.16~\mathrm{GeV}$$ 1<T/Tc<3,Tc∼0.16GeV ) and nonzero baryon densities (baryon chemical potential $$\mu _B<0.5~\mathrm{GeV}$$ μB<0.5GeV ) in an external uniform magnetic field ($$eB<0.5~\mathrm{GeV}^2$$ eB<0.5GeV2 ). Within FCM, the np high-temperature dynamics is embodied in the Polyakov loop and in the Debye mass due to the Color-Magnetic confinement. Analytic expressions for quark pressure and magnetic susceptibility were obtained. The expressions were represented as series and in integral form. Magnetic susceptibility was found to increase rapidly with temperature and slowly with density. The results at the zero density limit are in agreement with lattice data. |
