We report the measurement of collision rate coefficient for collisions between ultracold Cs atoms and low-energy $\mathrm{C}{\mathrm{s}}^{+}$ ions. The experiments are performed in a hybrid trap consisting of a magneto-optical trap (MOT) for Cs atoms and a Paul trap for $\mathrm{C}{\mathrm{s}}^{+}$ ions. The ion-atom collisions impart kinetic energy to the ultracold Cs atoms, resulting in their escape from the shallow MOT and, therefore, in a reduction in the number of Cs atoms in the MOT. By…

Collisional Cooling of Light Ions by Cotrapped Heavy Atoms.
The results suggest that the cooling of ions by localized cold atoms holds for any mass ratio, thereby enabling studies on a wider class of atom-ion systems irrespective of their masses.
Cooling of trapped ions by resonant charge exchange
The two most widely used ion cooling methods are laser cooling and sympathetic cooling by elastic collisions (ECs). Here we demonstrate another method of cooling ions that is based on resonant charge
Ultracold atom-ion collisions
Studies of charge transfer and total cross sections in elastic collisions of atom-ion alkali metals at ultralow temperatures are reported. Calculations for Na+Na{sup +} have been carried out with the
Dynamics of a Ground-State Cooled Ion Colliding with Ultracold Atoms.
The dynamics of a single ground-state cooled ion during few, to many, Langevin (spiraling) collisions with ultracold atoms are studied and a clear deviation from the Maxwell-Boltzmann distribution is observed, characterized by an exponential tail, to a power-law distribution best described by a Tsallis function.
Observation of cold collisions between trapped ions and trapped atoms.
Using Yb+ ions confined in a Paul trap and Yb atoms in a magneto-optical trap, charge-exchange collisions of several isotopes over three decades of collision energies down to 3 mueV (k_{B}x35 mK) are investigated.
Measurement of collisions between rubidium atoms and optically dark rubidium ions in trapped mixtures
ions in an overlapping Paul trap. In such a mixture,the ions are created from the MOT atoms and allowed to accumulate in the ion trap, which resultsin a signi cant reduction in the number of steady
Millikelvin reactive collisions between sympathetically cooled molecular ions and laser-cooled atoms in an ion-atom hybrid trap.
A study of cold reactive collisions between sympathetically cooled molecular ions and laser-cooled atoms in an ion-atom hybrid trap provides a test of classical models for reactions of molecular ions at the lowest energies reached thus far.
Collisional cooling of trapped ions with cold atoms: results and insights
We present a series of recent experimental and numerical results which allow us to propose and explain the mechanisms for collisional cooling of a trapped ion by sequential binary collisions with
Nondestructive detection of ions using atom-cavity collective strong coupling
We present a technique, based on atoms coupled to an optical cavity, for non-destructive detection of trapped ions. We demonstrate the vacuum-Rabi splitting (VRS), arising due to the collective
Cold hybrid ion-atom systems
Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single experimental setup have recently emerged as a new platform for fundamental research in quantum physics. This paper
