Hybrid quantum-classical simulations of semiclassical gravity
Carlos Fulgado-Claudio, Daniel González-Cuadra, Jose Beltrán Jiménez +1
We propose a hybrid quantum-classical algorithm for the simulation of real-time dynamics in interacting quantum field theories coupled to classical fields, focusing on the self-con…
A quasi-particle picture for entanglement cones and horizons in analogue cosmology
Carlos Fulgado-Claudio, Alejandro Bermudez
Although particle production in curved quantum field theories (cQFTs) is key to our understanding of the early universe and black hole physics, its direct observation requires extr…
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…
