On the Efimov Effect in Higher Partial Waves
K. Helfrich, H. -W. Hammer
Using the framework of effective field theory, we present a detailed study of the Efimov effect in higher partial waves for systems of two identical particles and a third distingui…
Resonant three-body physics in two spatial dimensions
K. Helfrich, H. -W. Hammer
We discuss the three-body properties of identical bosons exhibiting large scattering length in two spatial dimensions. Within an effective field theory for resonant interactions, w…
Three-body problem in heteronuclear mixtures with resonant interspecies interaction
K. Helfrich, H. -W. Hammer, D. S. Petrov
We use the zero-range approximation to study a system of two identical bosons interacting resonantly with a third particle. The method is derived from effective field theory. It re…
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…
