Experimental particle production in time-dependent spacetimes: a one-dimensional scattering problem
Marius Sparn, Elinor Kath, Nikolas Liebster +7
We experimentally study cosmological particle production in a two-dimensional Bose-Einstein condensate, whose density excitations map to an analog cosmology. The expansion of space…
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…
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…
