We derive the ground state energy up to the fourth order in the fine-structure constant α for the translation-invariant Pauli–Fierz Hamiltonian for a spinless electron coupled to the quantized radiation field. As a consequence, we obtain the non-analyticity of the ground state energy of the Pauli–Fierz operator for a single particle in the Coulomb field of a nucleus.
