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…
Accessing the topological Mott insulator in cold atom quantum simulators with realistic Rydberg dressing
Lorenzo Cardarelli, Sergi Julià-Farré, Maciej Lewenstein +2
The interplay between many-body interactions and the kinetic energy gives rise to rich phase diagrams hosting, among others, interaction-induced topological phases. These phases ar…
Revealing the topological nature of the bond order wave in a strongly correlated quantum system
Sergi Julià-Farré, Daniel González-Cuadra, Alexander Patscheider +5
We investigate the topological properties of the bond order wave phase arising in the extended Fermi-Hubbard model. In particular, we uncover a topological sector, which remained e…
Cold atoms meet lattice gauge theory
Monika Aidelsburger, Luca Barbiero, Alejandro Bermudez +19
The central idea of this review is to consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is…
Unsupervised machine learning of topological phase transitions from experimental data
Niklas Käming, Anna Dawid, Korbinian Kottmann +4
Identifying phase transitions is one of the key challenges in quantum many-body physics. Recently, machine learning methods have been shown to be an alternative way of localising p…
