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…
