In quark-gluon plasma (QGP), at high temperature the spontaneous generation of color magnetic fields, H^3(T), H^8(T) and usual magnetic field $H(T) is realized. Also, classical field - A_0(T) condensate directly related to the Polyakov loop…

Although at temperatures $T\gg \Lambda_{QCD}$ the quark-gluon plasma (QGP) is a gas of weakly interacting quasiparticles (modulo long-range magnetism), it is strongly interacting (sQGP) in the temperature range $(1-3) T_c$. One aspect of…
