Strong spin-exchange recombination of three weakly interacting Li atoms
J. -L. Li, T. Secker, P. M. A. Mestrom +1
We reveal a significant spin-exchange pathway in the three-body recombination process for ultracold lithium-7 atoms near a zero-crossing of the two-body scattering length. This new…
Three-body spin mixing in spin-1 Bose-Einstein condensates
P. M. A. Mestrom, J. -L. Li, V. E. Colussi +2
We study zero-energy collisions between three identical bosons with spin interacting via pairwise potentials. We quantify the corresponding three-body scattering hypervolum…
Three-body universality in ultracold -wave resonant mixtures
P. M. A. Mestrom, V. E. Colussi, T. Secker +2
We study three-body collisions within ultracold mixtures with resonant interspecies -wave interactions. Our results for the three-body effective interaction strength and decay r…
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…
Efficient three-body calculations with a two-body mapped grid method
T. Secker, J. -L. Li, P. M. A. Mestrom +1
We investigate the prospects of combining a standard momentum space approach for ultracold three-body scattering with efficient coordinate space schemes to solve the underlying two…
Van der Waals universality near a quantum tricritical point
P. M. A. Mestrom, V. E. Colussi, T. Secker +2
We study the three-body scattering hypervolume of atoms whose scattering length is on the order of or smaller than the typical range of the van der Waals…
Scattering hypervolume for ultracold bosons from weak to strong interactions
P. M. A. Mestrom, V. E. Colussi, T. Secker +1
The elastic scattering properties of three bosons at low energy enter the many-body description of ultracold Bose gases via the three-body scattering hypervolume . We study this…
Finite-range effects in Efimov physics beyond the separable approximation
Paul M. A. Mestrom, Thomas Secker, Ronen Kroeze +1
We study Efimov physics for three identical bosons interacting via a pairwise square-well potential, analyze the validity of the separable approximation as a function of the intera…
Efimov-van-der-Waals universality for ultracold atoms with positive scattering lengths
Paul M. A. Mestrom, Jia Wang, Chris H. Greene +1
We study the universality of the three-body parameters for systems relevant for ultracold quantum gases with positive -wave two-body scattering lengths. Our results account for…
