Collective excitation of a Bose-Einstein condensate by modulation of the atomic scattering length
S. E. Pollack, D. Dries, R. G. Hulet +5
We excite the lowest-lying quadrupole mode of a Bose-Einstein condensate by modulating the atomic scattering length via a Feshbach resonance. Excitation occurs at various modulatio…

Universality in Three- and Four-Body Bound States of Ultracold Atoms
Scott E. Pollack, Daniel Dries, Randall G. Hulet
Under certain circumstances, three or more interacting particles may form bound states. While the general few-body problem is not analytically solvable, the so-called Efimov trimer…
