M. Luttinger in 1964 as a model for the conduction of thermal currents in solids. The previous work [DL] contains a complete study of the \"free\" model in one spatial dimension along with a preliminary scattering result for convolution-type perturbations. This work complements the results obtained in [DL] by providing a detailed analysis of the perturbation theory for the one-dimensional thermal Hamiltonian. In more detail the following result are established: the regularity and decay properties for elements in the domain of the unperturbed thermal Hamiltonian; the determination of a class of self-adjoint and relatively compact perturbations of the thermal Hamiltonian; the proof of the existence and completeness of wave operators for a subclass of such potentials.", "revisions": [ { "version": "v1", "updated": "2021-02-21T13:38:53.000Z" } ], "analyses": { "subjects": [ "81Q10", "81Q05", "81Q15", "33C10" ], "keywords": [ "perturbation theory", "1d case", "one-dimensional thermal hamiltonian", "thermal currents", "wave operators" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
