We have attempted to build a parametric-based simplified and analytical model to map the interaction of quarks and gluons in the presence of magnetic field, which has been constrained by quark condensate and thermodynamical quantities like pressure, energy density, etc., obtained from the calculation of lattice quantum chromodynamics (QCDs). To fulfill that mapping, we have assumed a parametric temperature and magnetic field-dependent degeneracy factor, average energy, momentum and velocity of quarks and gluons. Implementing this QCD interaction in calculation of transport coefficient at finite magnetic field, we have noticed that magnetic field and interaction both are two dominating sources, for which the values of transport coefficients can be reduced. Though the methodology is not so robust, but with the help of its simple parametric expressions, one can get a quick rough estimation of any phenomenological quantity, influenced by temperature and magnetic field-dependent QCD interaction.

从非相互作用到相互作用的夸克 - 胶子等离子体在磁场及其流体特性下的图像

我们试图建立一个基于参数的简化和分析模型来映射夸克和胶子在磁场存在下的相互作用,磁场受到夸克凝聚和热力学量(如压力、能量密度等)的约束,从晶格量子色动力学(QCDs)的计算。为了实现该映射,我们假设了参数温度和磁场相关的简并因子、夸克和胶子的平均能量、动量和速度。在有限磁场下的传输系数计算中实施这种 QCD 相互作用,我们注意到磁场和相互作用都是两个主要来源,可以减少传输系数的值。虽然方法不是那么稳健,
