--- res: bibo_abstract: - We give a nonrigorous derivation of the nonlinear Boltzmann equation from the Schrödinger evolution of interacting fermions. The argument is based mainly on the assumption that a quasifree initial state satisfies a property called restricted quasifreeness in the weak coupling limit at any later time. By definition, a state is called restricted quasifree if the four-point and the eight-point functions of the state factorize in the same manner as in a quasifree state.@eng bibo_authorlist: - foaf_Person: foaf_givenName: László foaf_name: László Erdös foaf_surname: Erdös foaf_workInfoHomepage: http://www.librecat.org/personId=4DBD5372-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-5366-9603 - foaf_Person: foaf_givenName: Manfred foaf_name: Salmhofer, Manfred foaf_surname: Salmhofer - foaf_Person: foaf_givenName: Horng foaf_name: Yau, Horng-Tzer foaf_surname: Yau bibo_doi: 10.1023/B:JOSS.0000037224.56191.ed bibo_issue: 1-4 bibo_volume: 116 dct_date: 2004^xs_gYear dct_publisher: Springer@ dct_title: On the quantum Boltzmann equation@ ...
