Luttinger introduced a model for the quantum thermal transport. In this paper we study the spectral theory of the Hamiltonian operator associated to the Luttinger's model, with a special focus at the one-dimensional case. It is shown that the (so called) thermal Hamiltonian has a one-parameter family of self-adjoint extensions and the spectrum, the time-propagator group and the Green function are explicitly computed. Moreover, the scattering by convolution-type potentials is analyzed. Finally, also the associated classical problem is completely solved, thus providing a comparison between classical and quantum behavior. This article aims to be a first contribution in the construction of a complete theory for the thermal Hamiltonian.", "revisions": [ { "version": "v1", "updated": "2020-02-24T17:16:39.000Z" } ], "analyses": { "subjects": [ "81Q10", "81Q05", "81Q15", "33C10" ], "keywords": [ "thermal hamiltonian", "spectral theory", "1d case", "quantum thermal transport", "complete theory" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
