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…
Stabilization of Hubbard-Thouless pumps through nonlocal fermionic repulsion
Javier Argüello-Luengo, Manfred J. Mark, Francesca Ferlaino +3
Thouless pumping represents a powerful concept to probe quantized topological invariants in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard mode…
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…
Quantum Heat Engines with Carnot Efficiency at Maximum Power
Mohit Lal Bera, Sergi Julià-Farré, Maciej Lewenstein +1
Heat engines constitute the major building blocks of modern technologies. However, conventional heat engines with higher power yield lesser efficiency and vice versa and respect va…
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…
