Effective band-projected description of interacting quasiperiodic systems
Flavio Riche, Raul Liquito, Bruno Amorim +3
We study the interplay between electronic interactions and quasiperiodicity in a one-dimensional narrow-band system, focusing on ground-state and low-energy excitation properties.…

Fractal Quasicondensation in One Dimension
Flavio Riche, Miguel Gonçalves, Bruno Amorim +2
We unveil a novel mechanism for quasicondensation of hard-core bosons in the presence of quasiperiodicity-induced multifractal single-particle states. The new critical state, here…
