{"issue":"16","publisher":"American Physical Society","abstract":[{"lang":"eng","text":"We introduce a diagrammatic Monte Carlo approach to angular momentum properties of quantum many-particle systems possessing a macroscopic number of degrees of freedom. The treatment is based on a diagrammatic expansion that merges the usual Feynman diagrams with the angular momentum diagrams known from atomic and nuclear structure theory, thereby incorporating the non-Abelian algebra inherent to quantum rotations. Our approach is applicable at arbitrary coupling, is free of systematic errors and of finite-size effects, and naturally provides access to the impurity Green function. We exemplify the technique by obtaining an all-coupling solution of the angulon model; however, the method is quite general and can be applied to a broad variety of systems in which particles exchange quantum angular momentum with their many-body environment."}],"year":"2018","oa_version":"Preprint","department":[{"_id":"MiLe"}],"status":"public","article_number":"165301","date_created":"2019-04-17T10:53:38Z","citation":{"ieee":"G.
