This talk explores how unconventional lattice connectivity—from self-similar fractals to negatively curved hyperbolic graphs—reshapes quantum phenomena on the single- and many-body level. Geometric tuning enables transport regimes ranging from sub-diffusive to localized, governed by the interplay of fractal dimension and level-spacing distributions. In bosonic systems, hyperbolic curvature allows 2D lattices to mimic the Bose-Einstein condensation of 3D cubic systems, whereas fractal structures suppress condensation and can trigger condensate fragmentation.
