Asymptotics in Spin-Boson type models
Thomas Norman Dam, Jacob Schach Møller
In this paper we investigate a family of models for a qubit interacting with a bosonic field. More precisely, we find asymptotic limits of the Hamiltonian as the strength of the in…
Spin-Boson type models analysed using symmetries
Thomas Norman Dam, Jacob Schach Møller
In this paper we analyse a family of models for a qubit interacting with a bosonic field. These models have a parity symmetry, which enables them to have a ground state even in som…
Asymptotic Completeness in Quantum Field Theory: Translation Invariant Nelson Type Models Restricted to the Vacuum and One-Particle Sectors
Christian Gérard, Jacob Schach Møller, Morten Grud Rasmussen
Time-dependent scattering theory for a large class of translation invariant models, including the Nelson and Polaron models, restricted to the vacuum and one-particle sectors is st…
The translation Invariant Massive Nelson Model: II. The Continuous Spectrum Below the Two-boson Threshold
Jacob Schach Møller, Morten Grud Rasmussen
In this paper we continue the study of the energy-momentum spectrum of a class of translation invariant, linearly coupled, and massive Hamiltonians from non-relativistic quantum fi…
