论文摘要
使用一维粒子中的粒子（PIC）代码研究了电子温度对非均匀等离子体中非线性血浆振荡的影响。与传统的智慧相反，发现对于不均匀的血浆，存在电子温度的临界值，超出了波浪破裂。这一新型结果与当今的激光血浆实验相关，已经根据电子热压和背景不均匀性之间的相互作用进行了解释。
The effect of electron temperature on the space-time evolution of nonlinear plasma oscillations in an inhomogeneous plasma is studied using a one-dimensional particle-in-cell (PIC) code. In contrast to the conventional wisdom, it is found that for an inhomogeneous plasma, there exists a critical value of electron temperature beyond which wave breaking does not occur. This novel result, which is of relevance to present day laser plasma experiments, has been explained on the basis of interplay between electron thermal pressure and background inhomogeneity.
