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…
