The viscosity tensor of the magnetized one-component plasma, consisting of five independent shear viscosity coefficients, a bulk viscosity coefficient, and a cross coefficient, is computed using equilibrium molecular dynamics simulations and the Green-Kubo relations. A broad range of Coulomb coupling and magnetization strength conditions are studied. Magnetization is found to strongly influence the shear viscosity coefficients when the gyrofrequency exceeds the Coulomb collision frequency. Three regimes are identified as the Coulomb coupling strength and magnetization strength are varied. The Green-Kubo relations are used to separate kinetic and potential energy contributions to each viscosity coefficient, showing how each contribution depends upon the magnetization strength. The shear viscosity coefficient associated with the component of the pressure tensor parallel to the magnetic field, and the two coefficients associated with the component perpendicular to the magnetic field, are all found to merge to a common value at strong Coulomb coupling.

磁化强耦合单组分等离子体的粘度

使用平衡分子动力学模拟和格林-久保关系，计算了由五个独立的剪切粘度系数，体粘度系数和交叉系数组成的磁化单组分等离子体的粘度张量。研究了广泛的库仑耦合和磁化强度条件。当陀螺频率超过库仑碰撞频率时，发现磁化强烈地影响剪切粘度系数。随着库仑耦合强度和磁化强度的变化，确定了三种状态。Green-Kubo关系用于分离动能和势能对每个粘度系数的贡献，从而表明每种贡献如何取决于磁化强度。
