Observation of Efimov Universality across a Non-Universal Feshbach Resonance in \textsuperscript{39}K
Xin Xie, Michael J. Van de Graaff, Roman Chapurin +6
We study three-atom inelastic scattering in ultracold \textsuperscript{39}K near a Feshbach resonance of intermediate coupling strength. The non-universal character of such resonan…

Precision Test of the Limits to Universality in Few-Body Physics
Roman Chapurin, Xin Xie, Michael J. Van de Graaff +5
We perform precise studies of two- and three-body interactions near an intermediate-strength Feshbach resonance in at G. Precise measuremen…
