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 power worm 100 pack (IPR) and the Shannon entropy in the coordinate space.Those physical quantities were determined from a robust statistical study for the stationary density profiles of the interacting condensate.Localization was identified for each lattice type as a function of the potential depth.

Our analysis revealed a range of the potential depths for which the condensate density becomes localized, from partially at random lattice sites to fully in a single site.We found that localization in the case of five-fold rotational symmetry appears flexcon reverse osmosis water storage tank for (6ER,9ER), while it occurs in the interval (12ER,15ER) for octagonal and dodecagonal symmetries.
