直线上非线性Dirac方程孤立波的谱稳定性

On spectral stability of solitary waves of nonlinear Dirac equation on a line

Gregory Berkolaiko, Andrew Comech

摘要:

研究了一维非线性Dirac方程孤立波解的谱稳定性。我们专注于狄拉克方程与立方非线性,被称为索勒模型在(1+1)维,也被称为大规模的Gross-Neveu模型。数值计算了孤立波的线性化谱,结果表明孤立波是谱稳定的。我们证实了我们的结果,找到明确的表达式的几个特征函数。对于具有一般非线性项的非线性Dirac方程,某些解析结果是成立的.

英文摘要:

We study the spectral stability of solitary wave solutions to the nonlinear Dirac equation in one dimension. We focus on the Dirac equation with cubic nonlinearity, known as the Soler model in (1+1) dimensions and also as the massive Gross-Neveu model. Presented numerical computations of the spectrum of linearization at a solitary wave show that the solitary waves are spectrally stable. We corroborate our results by finding explicit expressions for several of the eigenfunctions. Some of the analytic results hold for the nonlinear Dirac equation with generic nonlinearity.
