Kramers degeneracy theorem in nonrelativistic QED

arXiv:0809.4471 · doi:10.1007/s11005-009-0313-8

Abstract

Degeneracy of the eigenvalues of the Pauli-Fierz Hamiltonian with spin 1/2 is proven by the Kramers degeneracy theorem. The Pauli-Fierz Hamiltonian at fixed total momentum is also investigated.
