Maxwell-Pauli和Maxwell-Schrodinger方程组行波解的存在性

Existence of Travelling Wave Solutions to the Maxwell-Pauli and Maxwell-Schrödinger Systems

Kim Petersen, Jan Philip Solovej

摘要:

研究了带电粒子与其自生电磁场相互作用的两种数学描述。第一个模型是忽略自旋与磁场相互作用的单体Maxwell-Schrödinger系统,第二个模型是包含自旋-场相互作用的单体Maxwell-Pauli系统。我们证明了这两个系统存在行波解,只要波的速度$|v|$不是太大。此外,我们观察到,这些解决方案的能量的行为类似于$\frac{mv^2}{2}$为小速度的粒子,这可以解释为说,粒子的有效质量是相同的,它的裸质量。

英文摘要:

We study two mathematical descriptions of a charged particle interacting with it's self-generated electromagnetic field. The first model is the one-body Maxwell-Schrödinger system where the interaction of the spin with the magnetic field is neglected and the second model is the related one-body Maxwell-Pauli system where the spin-field interaction is included. We prove that there exist travelling wave solutions to both of these systems provided that the speed $|v|$ of the wave is not too large. Moreover, we observe that the energies of these solutions behave like $\frac{mv^2}{2}$ for small velocities of the particle, which may be interpreted as saying that the effective mass of the particle is the same as it's bare mass.
