含自旋Pauli-Fierz哈密顿量的基态简并度

Ground state degeneracy of the Pauli-Fierz Hamiltonian with spin

F. Hiroshima, H. Spohn

摘要:

我们考虑一个电子,自旋1/2,最低限度地耦合到量子化的辐射场在非相对论近似,一种情况下定义的Pauli-Fierz哈密顿量$H$。没有外部势和$H$纤维根据总动量$p$。证明了当电荷$e$和总动量$p$足够小时,具有总动量$p$的$H$的基态子空间是二重简并的.我们还建立了基态子空间的总角动量为$\pm1/2$,并研究了限制外势的情况。

英文摘要:

We consider an electron, spin 1/2, minimally coupled to the quantized radiation field in the nonrelativistic approximation, a situation defined by the Pauli-Fierz Hamiltonian $H$. There is no external potential and $H$ fibers according to the total momentum $p$. We prove that the ground state subspace of $H$ with a total momentum $p$ is two-fold degenerate provided the charge $e$ and the total momentum $p$ are sufficiently small. We also establish that the total angular momentum of the ground state subspace is $\pm1/2$ and study the case of a confining external potential.
