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…
