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 …

We report on the observation of cold collisions between Li 6 atoms and Yb+ ions. This
combination of species has recently been proposed as the most suitable for reaching the …

We study the quantum dynamics of an ion confined in a radio-frequency trap in interaction
with either a Bose or spin-polarized Fermi gas. To this end, we derive quantum optical …

Experimental realizations of charged ions and neutral atoms in overlapping traps are
gaining increasing interest due to their wide research application ranging from chemistry at …

We demonstrated sympathetic cooling of a single ion in a buffer gas of ultracold atoms with
small mass. Efficient collisional cooling was realized by suppressing collision-induced …

We describe an apparatus where many species of ultracold atoms can be simultaneously
trapped and overlapped with many species of ions in a Paul trap. Several design …

Sympathetic cooling is the process of energy exchange between a system and a colder
bath. We investigate this fundamental process in an atom-ion experiment where the system …

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 …

The heat transfer characteristics of a confined gas are often quantified by anisotropic thermal
conductivity and are affected by near-wall accumulation. However, in non-equilibrium …

The effect of collision energy on the magnetically tuned 6 Li–6 Li Feshbach resonance (FR)
is investigated theoretically by using the coupled-channel (CC) method for the collision …
