 Title: Stability of Discrete Ground State Authors: Miyao, Tadahiro Browse this author Sasaki, Itaru Browse this author Keywords: Ground state discrete ground state generalized spinboson model Fock space Dereziński-Gérard model. Issue Date: 14-Sep-2004 Publisher: Department of Mathematics, Hokkaido University Journal Title: Hokkaido University Preprint Series in Mathematics Volume: 663 Start Page: 1 End Page: 29 Abstract: We present new criteria for a self-adjoint operator to have a ground state. As an application, we consider models of quantum particles'' coupled to a massive Bose field and prove the existence of a ground state of them, where the particle Hamiltonian does not necessarily have compact resolvent.
