标题： Dynamically screened strongly quantized electron transport in binary neutron-star merger

摘要： 我们研究在双中子星合并模拟中相关的磁化热密电子离子等离子体中的电子输运系数。 我们在双中子星合并的低密度、高温、高度磁化等离子体中计算电导率和热导率，其中电子出现量子振荡行为。 对于显著的热力学效应，我们考虑电子的零级朗道能级以计算导电性。 我们在存在磁场的情况下求解玻尔兹曼方程，以获得电导率和热导率的耗散分量。 耗散系数的公式考虑了在量化电子-离子散射率中的频率依赖动态屏蔽。 数值估计表明，光子传播子的动态屏蔽对电导率和热导率的影响是显著的。 我们观察到，动态屏蔽使电导率和热导率的最大值分别减少了三十倍和二十倍，导致这些系数的相应时间尺度减少。 电导率和热导率之间的共同比例因子也观察到与温度呈立方关系，违反了维德曼-弗兰茨定律。 显示英文摘要

摘要： We examine electron-transport coefficients in magnetized hot and dense electron-ion plasma relevant in binary neutron star merger simulation. We calculate electrical and thermal conductivities in low density, high temperature, highly magnetized plasma of binary neutron star mergers where quantum oscillatory behavior of electrons emerge. For pronounced thermodynamic effects, we consider zeroth Landau level population of electrons for the calculation of conductivity. We solve Boltzmann equation in presence of magnetic field to obtain the dissipative components of electrical and thermal conductivities. The dissipative coefficients are formulated considering frequency dependent dynamical screening in the quantized electron-ion scattering rate. Numerical estimations show that the effect of dynamical screening of photon propagator on electrical and thermal conductivities is pronounced. We observe that dynamical screening reduces the maxima of both the electrical and thermal conductivities by factors of thirty one and twenty respectively leading to a reduction in the corresponding time scales of these coefficients. The common scaling factor between electrical and thermal conductivity is also observed to follow cubic relationship with temperature violating Wiedemann-Franz law.
