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…
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…
Topological phase transitions for any taste in 2D quasiperiodic systems
Tiago S. Gonçalves, Miguel Gonçalves, Pedro Ribeiro +1
In this paper we explore the effects of quasiperiodicity in paradigmatic models of Chern insulators. We identify a plethora of topological phase transitions and characterize them b…
The Haldane model under quenched disorder
Miguel Gonçalves, Pedro Ribeiro, Eduardo V. Castro
We study the half-filled Haldane model with Anderson and binary disorder and determine its phase diagram, as a function of the Haldane flux and staggered sub-lattice potential, for…
Theoretical guidelines to create and tune electric skyrmions
M. A. P. Gonçalves, Carlos Escorihuela-Sayalero, Pablo García-Fernández +2
Magnetic skyrmions are mesmerizing spin textures with peculiar topological and dynamical properties, typically the product of competing interactions in ferromagnets, and with great…
