A higher-order topological twist on cold-atom SO(5) Dirac fields
A. Bermudez, D. González-Cuadra, S. Hands
Ultracold Fermi gases of spin-3/2 atoms provide a clean platform to realise SO(5) models of 4-Fermi interactions in the laboratory. By confining the atoms in a two-dimensional Rama…
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…
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…
Topological quantum critical points in the extended Bose-Hubbard model
Joana Fraxanet, Daniel González-Cuadra, Tilman Pfau +3
The combination of topology and quantum criticality can give rise to an exotic mix of counterintuitive effects. Here, we show that unexpected topological properties take place in a…
Universal quantum computation and quantum error correction with ultracold atomic mixtures
Valentin Kasper, Daniel González-Cuadra, Apoorva Hegde +7
Quantum information platforms made great progress in the control of many-body entanglement and the implementation of quantum error correction, but it remains a challenge to realize…
solitons in intertwined topological phases
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
Topological phases of matter can support fractionalized quasi-particles localized at topological defects. The current understanding of these exotic excitations, based on the celebr…
Strongly Correlated Bosons on a Dynamical Lattice
Daniel González-Cuadra, Przemysław R. Grzybowski, Alexandre Dauphin +1
We study a one-dimensional system of strongly correlated bosons on a dynamical lattice. To this end, we extend the standard Bose-Hubbard Hamiltonian to include extra degrees of fre…
