Amorphous quantum magnets in a two-dimensional Rydberg atom array
Sergi Julià-Farré, Joseph Vovrosh, Alexandre Dauphin
Amorphous solids, i.e., systems which feature well-defined short-range properties but lack long-range order, constitute an important research topic in condensed matter. While their…

Frustrated extended Bose-Hubbard model and deconfined quantum critical points with optical lattices at the anti-magic wavelength
Niccolò Baldelli, Cesar R. Cabrera, Sergi Julià-Farré +2
The study of geometrically frustrated many-body quantum systems is of central importance to uncover novel quantum mechanical effects. We design a scheme where ultracold bosons trap…

Self-Trapped Polarons and Topological Defects in a Topological Mott Insulator
Sergi Julià-Farré, Markus Müller, Maciej Lewenstein +1
Many-body interactions in topological quantum systems can give rise to new phases of matter, which simultaneously exhibit both rich spatial features and topological properties. In…
