Binding condition for a general class of quantum field Hamiltonians
Christian Gérard, Itaru Sasaki
We consider a system of a quantum particle interacting with a quantum field and an external potential $V(\bx)$. The Hamiltonian is defined by a quadratic form $H^V = H^0 + V(\bx)$,…

On the ionization energy of the semi-relativistic Pauli-Fierz model for a single particle
Fumio Hiroshima, Itaru Sasaki
A semi-relativistic Pauli-Fierz model is defined by the sum of the free Hamiltonian of a Boson Fock space, an nuclear potential and a relativistic kinetic energy: $…
