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…

Observation of a Halo Trimer in an Ultracold Bose-Fermi Mixture

Alexander Y. Chuang, Huan Q. Bui, Arthur Christianen +5

The quantum mechanics of three interacting particles gives rise to interesting universal phenomena, such as the staircase of Efimov trimers predicted in the context of nuclear phys…

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…
