A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

This review is concerned with the physics and chemistry associated with the interactions,
collisions, and reactions of ultracold molecules, that is, molecules having translational …

Photoassociation of molecules out of an ultracold gas was thefirst successful approach to
create a gas of molecules in the electronic ground state at translational temperatures in the …

Translationally cold, spatially localised molecular ions prepared by sympathetic cooling with
laser-cooled atomic ions in ion traps have recently found a wide range of applications in …

We present a new method for the generation of rotationally and vibrationally state-selected,
translationally cold molecular ions in ion traps. Our technique is based on the state-selective …

At temperatures close to absolute zero, the molecular reactions and collisions are
dominantly governed by quantum mechanics. Remarkable quantum phenomena such as …

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

A fundamental question in the study of chemical reactions is how reactions proceed at a
collision energy close to absolute zero. This question is no longer hypothetical: quantum …

1. INTRODUCTION Photoassociation, forming molecules from ultracold atoms using laser
light, is a prime example of coherent control: The process is complex and poses many …

Ultracold gases of three distinguishable particles with large scattering lengths are expected
to show rich few-body physics related to the Efimov effect. We have created three different …
