Emergent Kitaev materials in synthetic Fermi-Hubbard bilayers
Daniel González-Cuadra, Alejandro Bermudez
We investigate the emergence of bond-directional spin-spin interactions in a synthetic Fermi-Hubbard bilayer that can be realized with ultracold fermions in Raman optical lattices.…
Interacting Dirac fields in an expanding universe: dynamical condensates and particle production
Carlos Fulgado-Claudio, Pablo Sala, Daniel González-Cuadra +1
The phenomenon of particle production for quantum field theories in curved spacetimes is crucial to understand the large-scale structure of a universe from an inflationary epoch. I…
Interacting second-order topological insulators in one-dimensional fermions with correlated hopping
A. Montorsi, U. Bhattacharya, Daniel González-Cuadra +3
Higher-order topological crystalline phases in low-dimensional interacting quantum systems represent a challenging and largely unexplored research topic. Here, we derive a Hamilton…
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…
Higher-order topological quantum paramagnets
Daniel González-Cuadra
Quantum paramagnets are strongly-correlated phases of matter where competing interactions frustrate magnetic order down to zero temperature. In certain cases, quantum fluctuations…
Devil's staircase of topological Peierls insulators and Peierls supersolids
Titas Chanda, Daniel González-Cuadra, Maciej Lewenstein +2
We consider a mixture of ultracold bosonic atoms on a one-dimensional lattice described by the XXZ-Bose-Hubbard model, where the tunneling of one species depends on the spin state…
The rotor Jackiw-Rebbi model: a cold-atom approach to chiral symmetry restoration and quark confinement
Daniel González-Cuadra, Alexandre Dauphin, Monika Aidelsburger +2
Understanding the nature of confinement, as well as its relation with the spontaneous breaking of chiral symmetry, remains one of the long-standing questions in high-energy physics…
Dynamical solitons and boson fractionalization in cold-atom topological insulators
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
We study the Bose-Hubbard model at incommensurate densities, which describes a one-dimensional system of interacting bosons whose tunneling is dressed by a dynamical…
Robust topological order in fermionic gauge theories: from Aharonov-Bohm instability to soliton-induced deconfinement
Daniel González-Cuadra, Luca Tagliacozzo, Maciej Lewenstein +1
Topologically-ordered phases of matter, although stable against local perturbations, are usually restricted to relatively small regions in phase diagrams. Their preparation require…
Symmetry-Breaking Topological Insulators in the Bose-Hubbard Model
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +3
In this work, we study a one-dimensional model of interacting bosons coupled to a dynamical field, the Bose-Hubbard model, and analyze the interplay b…
