研究了无碰撞均匀磁化量子等离子体中的非线性磁声波。采用双流体量子磁流体动力学模型(QMHD),利用约化微扰法导出磁声波的Korteweg de弗里斯(KdV)方程。研究了等离子体密度和磁场强度对量子等离子体中磁声孤波结构的影响。数值结果也适用于解释稠密天体物理等离子体中非线性磁声波传播的某些方面。
Nonlinear magnetoacoustic waves in collisionless homogenous, magnetized quantum plasma is studied. Two fluid quantum magneto-hydrodynamic model (QMHD) is employed and reductive perturbation method is used to derive Korteweg de Vries (KdV) equation for magnetoacoustic waves. The effects of plasma density and magnetic field intensity are investigated on magnetoacoustic solitary structures in quantum plasma. The numerical results are also presented, which are applicable to explain some aspects of the propagation of nonlinear magnetoacosutic wave in dense astrophysical plasma situations.
