Fermion production at the boundary of an expanding universe: a cold-atom gravitational analogue
Carlos Fulgado-Claudio, Jose M. Sánchez Velázquez, Alejandro Bermudez
We study the phenomenon of cosmological particle production of Dirac fermions in a Friedman-Robertson-Walker spacetime, focusing on a (1+1)-dimensional case in which the evolution…
Topological chiral currents in the Gross-Neveu model extension
E. Tirrito, M. Lewenstein, A. Bermudez
We unveil an interesting connection of Lorentz-violating quantum field theories, studied in the context of the standard model extension, and Hubbard-type models of topological crys…
Large- Chern insulators: lattice field theory and quantum simulation approaches to correlation effects in the quantum anomalous Hall effect
L. Ziegler, E. Tirrito, M. Lewenstein +2
Four-Fermi quantum field theories in (2+1) dimensions lie among the simplest models in high-energy physics, the understanding of which requires a non-perturbative lattice formulati…
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…
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…
