Three-body losses of a polarized Fermi gas near a p-wave Feshbach resonance in effective field theory
Marcel Schmidt, Hans-Werner Hammer, Lucas Platter
We study three-body recombination of fully spin-polarized Li atoms that are interacting resonantly in relative p-waves. Motivated by a recent experiment, we focus on negative…
Lindblad Equation for the Inelastic Loss of Ultracold Atoms
Eric Braaten, H. -W. Hammer, G. Peter Lepage
The loss of ultracold trapped atoms due to deeply inelastic reactions has previously been taken into account in effective field theories for low-energy atoms by adding local anti-H…
Universal Two-body Physics in Dark Matter near an S-wave Resonance
Eric Braaten, H. -W. Hammer
The dark matter annihilation rate at small relative velocities can be amplified by a large boost factor using various mechanisms, including Sommerfeld enhancement, resonance enhanc…
Renormalization in the Three-body Problem with Resonant P-wave Interactions
Eric Braaten, P. Hagen, H. -W. Hammer +1
Resonant P-wave interactions can be described by a minimal zero-range model defined by a truncated effective range expansion, so that the only 2-body interaction parameters are the…
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…
Efimov Physics in 6Li Atoms
Eric Braaten, H. -W. Hammer, Daekyoung Kang +1
A new narrow 3-atom loss resonance associated with an Efimov trimer crossing the 3-atom threshold has recently been discovered in a many-body system of ultracold 6Li atoms in the t…
Enhanced Dimer Relaxation in an Atomic/Molecular BEC
Eric Braaten, H. -W. Hammer
We derive a universal formula for the rate constant βfor relaxation of a shallow dimer into deeply-bound diatomic molecules in the case of atoms with a large scattering length a. W…
