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…
The multichannel nature of three-body recombination for ultracold K
T. Secker, J. -L. Li, P. M. A. Mestrom +1
We develop a full multichannel spin model in momentum space to investigate three-body recombination of identical alkali-metal atoms colliding in a magnetic field. The model combine…
Cumulant theory of the unitary Bose gas: Prethermal and Efimovian dynamics
V. E. Colussi, H. Kurkjian, M. Van Regemortel +4
We study the quench of a degenerate ultracold Bose gas to the unitary regime, where interactions are as strong as allowed by quantum mechanics. We lay the foundations of a cumulant…
Pair formation in quenched unitary Bose gases
S. Musolino, V. E. Colussi, S. J. J. M. F. Kokkelmans
We study a degenerate Bose gas quenched to unitarity by solving a many-body model including three-body losses and correlations up to second order. As the gas evolves in this strong…
Bunching, clustering, and the buildup of few-body correlations in a quenched unitary Bose gas
V. E. Colussi, B. E. van Zwol, J. P. D'Incao +1
We study the growth of two- and three-body correlations in an ultracold Bose gas quenched to unitarity. This is encoded in the dynamics of the two- and three-body contacts analyzed…
From coherent collective excitation to Rydberg blockade on an atom chip
Julius de Hond, Rick van Bijnen, S. J. J. M. F. Kokkelmans +3
Using time-resolved measurements, we demonstrate coherent collective Rydberg excitation crossing over into Rydberg blockade in a dense and ultracold gas trapped at a distance of 10…
