Third-order topological insulator induced by disorder
Hugo Lóio, Miguel Gonçalves, Pedro Ribeiro +1
We have found the first instance of a third-order topological Anderson insulator (TOTAI). This disorder-induced topological phase is gapped and characterized by a quantized octupol…
Incommensurability enabled quasi-fractal order in 1D narrow-band moiré systems
Miguel Gonçalves, Bruno Amorim, Flavio Riche +2
We demonstrate that quasiperiodicity can radically change the ground state properties of 1D moiré systems with respect to their periodic counterparts. By studying an illustrative e…
Short-range interactions are irrelevant at the quasiperiodic-driven Luttinger Liquid to Anderson Glass transition
Miguel Gonçalves, Jedediah H. Pixley, Bruno Amorim +2
We show that short-range interactions are irrelevant around gapless ground-state delocalization-localization transitions driven by quasiperiodicity in interacting fermionic chains.…
Quasiperiodicity-induced enhancement of superconductivity in one-dimensional critical systems
Ricardo Oliveira, Miguel Gonçalves, Pedro Ribeiro +2
We show that quasiperiodicity can enhance superconductivity in one-dimensional narrow-band systems with s-wave pairing. Using a generalized Aubry-André-Harper model featuring quasi…
Delocalization of topological surface states by diagonal disorder in nodal loop semimetals
João Silva, Miguel A. N. Araújo, Miguel Gonçalves +2
The effect of Anderson diagonal disorder on the topological surface (``drumhead'') states of a Weyl nodal loop semimetal is addressed. Since diagonal disorder breaks chiral symmetr…
Critical phase dualities in 1D exactly-solvable quasiperiodic models
Miguel Gonçalves, Bruno Amorim, Eduardo V. Castro +1
We propose a solvable class of 1D quasiperiodic tight-binding models encompassing extended, localized, and critical phases, separated by nontrivial mobility edges. Limiting cases i…
