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…

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…
