Functional integral approach to semi-relativistic Pauli-Fierz models [PDF]
Fumio HiroshimaBy means of functional integrations spectral properties of semi-relativistic Pauli-Fierz Hamiltonians in quantum electrodynamics is considered. Two self-adjoint extensions of a semi-relativistic Pauli-Fierz Hamiltonian are defined. An essential self-adjointness, a spatial decay of bound states, a Gaussian domination of the ground state and the existence of a measure associated with the ground state are shown.View original: http://arxiv.org/abs/1304.4735
