  bibo_abstract:
  - We introduce a Diagrammatic Monte Carlo (DiagMC) approach to complex molecular
    impurities with rotational degrees of freedom interacting with a many-particle
    environment. The treatment is based on the 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 works 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 quantum impurities possessing angular momentum degrees of
    freedom. @eng
