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…
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…
Resonance triplet dynamics in the quenched unitary Bose gas
J. van de Kraats, D. J. M. Ahmed-Braun, V. E. Colussi +1
The quenched unitary Bose gas is a paradigmatic example of a strongly interacting out-of-equilibrium quantum system, whose dynamics become difficult to describe theoretically due t…
Resonance-facilitated three-channel p-wave scattering
Denise Ahmed-Braun, Paul Julienne, Servaas Kokkelmans
Feshbach resonances of arbitrary width are typically described in terms of two-channel models. Within these models, one usually considers a single dressed resonance, with the optio…
Emergent s-wave interactions between identical fermions in quasi-one-dimensional geometries
Kenneth G. Jackson, Colin J. Dale, Jeff Maki +5
Orbital degrees of freedom play an essential role in metals, semiconductors, and strongly confined electronic systems. Experiments with ultracold atoms have used highly anisotropic…
Probing open- and closed-channel p-wave resonances
Denise J. M. Ahmed-Braun, Kenneth G. Jackson, Scott Smale +5
We study the near-threshold molecular and collisional physics of a strong K p-wave Feshbach resonance through a combination of measurements, numerical calculations, and mode…
Multichannel effects in the Efimov regime from broad to narrow Feshbach resonances
T. Secker, D. J. M. Ahmed-Braun, P. M. A. Mestrom +1
We study Efimov physics of three identical bosons with pairwise multichannel interactions for Feshbach resonances of adjustable width. We find that the two-body multichannel nature…
