We investigate the emergence of localization in a weakly interacting Bose gas confined in quasicrystalline lattices with three different rotational symmetries: five, eight, and twelve.The analysis, performed at a mean field level and from which localization is detected, relies on the study of two observables: the inverse participation ratio berkley
The reliability and comparability of international migration statistics belong to the most important statistical issues due to the importance of correct dimensioning of the migration flows and stocks for effective and perdieme lingerie timely design of effective policy measures.This paper presents an assessment of the migration statistics provided
