We report on three-body recombination of a single trapped Rb(+) ion and two neutral Rb atoms in an ultracold atom cloud. We observe that the corresponding rate coefficient K(3) depends on collision energy and is about a factor of 1000 larger than for three colliding neutral Rb atoms. In the three-body recombination process large energies up to several 0.1 eV are released leading to an ejection of the ion from the atom cloud. It is sympathetically recooled back into the cloud via elastic binary…

Three-body reaction dynamics in cold atom-ion experiments

Over the recent years a new research field emerged that combines technologies for cooling and trapping of neutral atoms and charged ions in one experimental apparatus. These atom-ion hybrid traps

Two-body and three-body dynamics in atom-ion experiments

During the last few decades, the two fields of ultracold neutral atoms and of single trapped ions have undergone an amazing development. The incorporation of both these systems into a single

Life and death of a cold BaRb+ molecule inside an ultracold cloud of Rb atoms

We study the evolution of a single BaRb$^+$ molecule while it continuously collides with ultracold Rb atoms. The initially weakly-bound molecule can undergo a sequence of elastic, inelastic,

Inelastic collision dynamics of a single cold ion immersed in a Bose-Einstein condensate

We investigate inelastic collision dynamics of a single cold ion in a Bose-Einstein condensate. We observe rapid ion-atom-atom three-body recombination leading to formation of weakly bound molecular

Communication: Classical threshold law for ion-neutral-neutral three-body recombination.

TLDR
A threshold law for the three-body recombination cross section is obtained and the derived threshold law predicts the formation of weakly bound dimers, with binding energies comparable to the collision energy of the collisional partners.

Shedding Light on Three-Body Recombination in an Ultracold Atomic Gas

Three-body recombination is a prime example of the fundamental interaction between three particles. Due to the complexity of this process it has resisted a comprehensive description. Experimental

Ultracold Atom-Ion Systems in Hybrid Traps

This thesis deals with the theoretical description of a hybrid system of an ultracold neutral atom and a single ion. These hybrid atom-ion systems have attracted significant interest in recent years.

Radiative emission during cold collisions between trapped laser-cooled Rb atoms and alkaline-earth ions (Ca+, Sr+, Ba+) and Yb+, and between Li and Yb+, are studied theoretically, using accurate

Spectral properties of a three-body atom-ion hybrid system

We consider a hybrid atom-ion system consisting of a pair of bosons interacting with a single ion in a quasi-one-dimensional trapping geometry. Building upon a model potential for the atom-ion

TLDR
Results show that the method can determine the scale of the network by itself, and achieves better performance, than the proposed DDWDS.
