Ground state degeneracy of the Pauli–Fierz Hamiltonian with spin
Ground state degeneracy of the Pauli–Fierz Hamiltonian with spin
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 as / H v dp according to the total momentum p.We prove that the ground state subspace of …
