Coupled-channels method for the scattering hypervolume in ultracold atomic three-body collisions
P. J. P. Kersbergen, J. van de Kraats, D. J. M. Ahmed-Braun +1
We introduce a novel coupled-channels method for elastic three-body scattering in systems of identical bosonic alkali-metal atoms. The approach relies on the numerically exact two-…

Probing non-Gaussian correlations through entanglement generation in a many-body quantum system
J. van de Kraats, D. J. M. Ahmed-Braun, V. E. Colussi +1
In understanding strongly correlated quantum systems, quantifying the non-Gaussian nature of interparticle correlations is invaluable. We show that, for a uniform quantum gas, ther…

Non-equilibrium dynamics and atom-pair coherence in strongly interacting Bose-Fermi mixtures
J. van de Kraats, D. J. M. Ahmed-Braun, V. E. Colussi +1
Theoretical treatments of non-equilibrium dynamics in strongly interacting Bose-Fermi mixtures are complicated by the inherent non-Gaussian nature of the vacuum two-body physics, i…
