In a strong magnetic field, the hot dense quark matter is investigated in the Polyakov Nambu–Jona–Lasinio model. The value of a traced Polyakov loop is found as a nonmonotonous function of the chemical potential at lower magnetic fields and as a monotonous increasing function at high magnetic fields. The decreasing pseudocritical temperatures for the chiral restoration and the deconfinement crossover are reproduced by a temperature-and-magnetic-field-dependent coupling constant to reflect the inverse magnetic catalysis. Furthermore, the deconfined but chiral broken phase can be observed in the split region of the T χ and T ϕ .

Polyakov Nambu–Jona–Lasinio模型中的磁化热致密夸克物质

在强磁场中，在Polyakov Nambu–Jona–Lasinio模型中研究了热致密夸克物质。发现跟踪的Polyakov回路的值是在较低磁场下化学势的非单调函数，在高磁场下是化学势的单调递增函数。用于手性修复和脱限跨界的伪临界温度的降低是通过依赖于温度和磁场的耦合常数来再现的，以反映逆磁催化作用。此外，在Tχ和T ϕ的分裂区域中可以观察到限定的但手性的断裂相。
