Local Density of States as a Probe of Multifractality in Quasiperiodic Moiré Materials
Ricardo Oliveira, Nicolau Sobrosa, Pedro Ribeiro +2
Quasiperiodic moiré materials provide a new platform for realizing critical electronic states, yet a direct and experimentally practical method to characterize this criticality ha…

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 th…

Instability of QBC systems to Topological Anderson Insulating phases
Nicolau Sobrosa, Miguel Gonçalves, Eduardo V. Castro
Here we study the instabilities of a quadratic band crossing system to Chern insulating states and uncorrelated disorder. We determined the phase diagram in the plane of topologica…
