Resonant Atom-Dimer Relaxation in Ultracold Atoms
Kerstin Helfrich, H. -W. Hammer
Three-body systems with large scattering length display universal phenomena associated with a discrete scaling symmetry. These phenomena include resonant enhancement of three-body…
Three-body Recombination of Lithium-6 Atoms with Large Negative Scattering Lengths
Eric Braaten, H. -W. Hammer, Daekyoung Kang +1
The 3-body recombination rate at threshold for distinguishable atoms with large negative pair scattering lengths is calculated in the zero-range approximation. The only parameters…
Three-Body Recombination of Identical Bosons with a Large Positive Scattering Length at Nonzero Temperature
Eric Braaten, H. -W. Hammer, Daekyoung Kang +1
For identical bosons with a large scattering length, the dependence of the 3-body recombination rate on the collision energy is determined in the zero-range limit by universal func…
Few-Body Effects in Cold Atoms and Limit Cycles
H. -W. Hammer
Physical systems with a large scattering length have universal properties independent of the details of the interaction at short distances. Such systems can be realized in experime…
Efimov Physics in Cold Atoms
Eric Braaten, H. -W. Hammer
Atoms with a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interactions at short distances. In the 2-at…
Effective Range Corrections to Three-Body Recombination for Atoms with Large Scattering Length
H. -W. Hammer, Timo A. Lahde, L. Platter
Few-body systems with large scattering length a have universal properties that do not depend on the details of their interactions at short distances. The rate constant for three-bo…
