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-…
Effect of Population Imbalance on Vortex Mass in Superfluid Fermi Gases
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
One of the fundamental parameters associated with quantized vortices in superfluids is the vortex mass, which is the inertia of a vortex. As of yet, this mass has not been observed…
Vortex Mass in Superfluid Fermi Gases along the BEC-BCS Crossover
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
Vortex mass is a key concept in the study of superfluid dynamics, referring to the inertia of vortices in a superfluid, which affects their motion and behavior. Despite being an im…
Optical response of the supersolid polaron
Laurent H. A. Simons, Ralf Klemt, Tilman Pfau +2
The ground-state properties of the supersolid polaron consisting of a neutral impurity immersed in a dipolar supersolid have recently been studied. Here, the optical response of an…
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…
