Quasiperiodicity hinders ergodic Floquet eigenstates
Miguel Gonçalves, Pedro Ribeiro, Ivan M. Khaymovich
Quasiperiodic systems in one dimension can host non-ergodic states, e.g. localized in position or momentum. Periodic quenches within localized phases yield Floquet eigenstates of t…
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…
Certain Extensions of Results of Siegel, Wilton and Hardy
Pedro Ribeiro, Semyon Yakubovich
Recently, Dixit et al. established a very elegant generalization of Hardy's Theorem concerning the infinitude of zeros that the Riemann zeta function possesses at its critical line…
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…
