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 distinguishable particle. Depending on the total angular momentum L, the two identical particles must be bosons or fermions. We derive analytical expressions for the elastic and inelastic atom–dimer scattering cross sections as well as the atom–dimer relaxation rate at the dimer breakup threshold. For the experimentally most…

Five-Body Efimov Effect and Universal Pentamer in Fermionic Mixtures.

The five-body Efimov effect for this system in the regime where any of its subsystem is non-Efimovian is predicted, which is smaller than the corresponding 2+1 and 3+1 thresholds.

Few-Body Physics in Quantum Gases

Few-body effects play an important role for the understanding of ultracold quantum gases. We make use of an effective field theory approach to investigate various aspects of universal few-body

Few-body physics in resonantly interacting ultracold quantum gases

We provide a general discussion on the importance of three-body Efimov physics for strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical representation, we discuss a

Three-particle bound states in a finite volume: Unequal masses and higher partial waves

An explicit expression for the finite-volume energy shift of shallow three-body bound states for non-identical particles is obtained in the unitary limit. The inclusion of the higher partial waves is

A quantum-mechanical three-body problem for two identical fermions of mass m and a distinct particle of mass m1 in the universal limit of zero-range two-body interaction is studied. For the

Mass-imbalanced fermionic mixture in a harmonic trap

The mass-imbalanced fermionic mixture is studied, where $N\le5$ identical fermions interact resonantly with an impurity, a distinguishable atom. The shell structure is explored, and the physics of a

These experiments revealed that the previously undetermined three-body parameter introduced in the Efimov theory to stabilise the three- body attraction typically scales with the range of atomic interactions.

Three-body problem in heteronuclear mixtures with resonant interspecies interaction

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 reduces the

Dimer-atom scattering between two identical fermions and a third particle

We use the diagrammatic T-matrix approach to analyze the three-body scattering problem between two identical fermions and a third particle (which could be a different species of fermion or a boson).

Renormalization of the Three-Body System with Short-Range Interactions

We discuss renormalization of the nonrelativistic three-body problem with short-range forces. The problem becomes nonperturbative at momenta of the order of the inverse of the two-body scattering

Resonant atom-dimer relaxation in ultracold atoms

Three-body systems with large scattering length display universal phenomena associated with a discrete scaling symmetry. These phenomena include resonant enhancement of three-body loss rates when an

Atom-dimer scattering and long-lived trimers in fermionic mixtures.

It is found that there is a peculiar atom-dimer p-wave resonance which can be tuned by changing the frequency of the confinement, and this mechanism allows for switching the p- wave interaction between a K atom and Li-K dimer from attractive to repulsive, and forming a weakly bound trimer with unit angular momentum.
