Curved and expanding spacetime geometries in Bose-Einstein condensates
Mireia Tolosa-Simeón, Álvaro Parra-López, Natalia Sánchez-Kuntz +9
Phonons have the characteristic linear dispersion relation of massless relativistic particles. They arise as low energy excitations of Bose-Einstein condensates and, in nonhomogene…
Scalar quantum fields in cosmologies with 2+1 spacetime dimensions
Natalia Sánchez-Kuntz, Álvaro Parra-López, Mireia Tolosa-Simeón +2
Motivated by the possibility to use Bose-Einstein condensates as quantum simulators for spacetime curvature, we study a massless relativistic scalar quantum field in spatially curv…
Quantum field simulator for dynamics in curved spacetime
Celia Viermann, Marius Sparn, Nikolas Liebster +9
The observed large-scale structure in our Universe is seen as a result of quantum fluctuations amplified by spacetime evolution. This, and related problems in cosmology, asks for a…
Spatial entanglement in interacting Bose-Einstein condensates
N. Sánchez-Kuntz, S. Floerchinger
The entanglement between spatial regions in an interacting Bose-Einstein condensate is investigated using a quantum field theoretic formalism. Regions that are small compared to th…
The measure of PBR's reality
Natalia Sánchez-Kuntz, Eduardo Nahmad-Achar
We review the Pusey-Barret-Rudolph (PBR) theorem\cite{PBR} and their setup, and arrive to the conclusion that the reality of a quantum state is intrinsically attached to the me…
