论文摘要
已经研究了弱磁化夸克 - 胶质血浆中的热传输系数，已在准粒子模型的范围内进行了研究，以编码现实状态方程的效果。弱磁场的存在导致与介质中热传输相关的霍尔型电导率。一种有效的协变量动力学理论已被用来量化热量耗散，同时将平均场贡献纳入培养基。根据Wiedemann-Franz定律，已经探索了弱磁化介质中热传输和电荷传输的相互作用。在过渡温度接近的温度方案中，已经观察到了对Wiedemann-Franz定律的强烈侵犯。还研究了在强磁场极限中导热率的行为。可以观察到，状态的磁场和方程对介质中的热耗散都有重大影响。
The thermal transport coefficients in a weakly magnetized quark-gluon plasma have been investigated within the ambit of a quasiparticle model to encode the effects of the realistic equation of state. The presence of a weak magnetic field leads to the Hall-type conductivity associated with thermal transport in the medium. An effective covariant kinetic theory has been employed to quantify the thermal dissipation while incorporating the mean field contributions in the medium. The interplay of thermal transport and electric charge transport in the weakly magnetized medium has been explored in terms of the Wiedemann-Franz law. Strong violation of the Wiedemann-Franz law has been observed in temperature regimes near to the transition temperature. The behaviour of thermal conductivity in the strong magnetic field limit has also been studied. It is observed that both the magnetic field and equation of state have a significant impact on the thermal dissipation in the medium.
