Fragmentation Temperature of 1D and 3D Quantum Droplets in a BEC Mixture
Jeroen Van Loock, Denise Ahmed-Braun, Jacques Tempere
In a mixture of two Bose-Einstein condensates, the interactions can be tuned such that self-bound objects called quantum droplets appear. Whereas the ground states of such quantum…
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-…
Effective Three-Boson Interactions using a Separable Potential
Corinne Beckers, Jacques Tempere, Jeff Maki +1
Effective field theories (EFTs) are widely used to study many-body systems by describing two-body interactions using zero-ranged contact potentials. However, when extended to three…
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…
