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.…

Ground state and excitations of quasiperiodic 1D narrow-band moiré systems: a mean field approach
Nicolau Sobrosa, Miguel Gonçalves, Bruno Amorim +2
We demonstrate that a mean field approximation can be confidently employed in quasiperiodic moiré systems to treat interactions and quasiperiodicity on equal footing. We obtain the…
