Higher-order topological Peierls insulator in a two-dimensional atom-cavity system
Joana Fraxanet, Alexandre Dauphin, Maciej Lewenstein +2
In this work, we investigate a two-dimensional system of ultracold bosonic atoms inside an optical cavity, and show how photon-mediated interactions give rise to a plaquette-ordere…
Topological stripe state in an extended Fermi-Hubbard model
Sergi Julià-Farré, Lorenzo Cardarelli, Maciej Lewenstein +2
Interaction-induced topological systems have attracted a growing interest for their exotic properties going beyond the single-particle picture of topological insulators. In particu…
Topological Hofstadter Insulators in a Two-Dimensional Quasicrystal
Duc-Thanh Tran, Alexandre Dauphin, Nathan Goldman +1
We investigate the properties of a two-dimensional quasicrystal in the presence of a uniform magnetic field. In this configuration, the density of states (DOS) displays a Hofstadte…
