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 …

Experimental setups that study laser-cooled ions immersed in baths of ultracold atoms
merge the two exciting and well-established fields of quantum gases and trapped ions …

In this work, we present a method for measuring the motional state of a two-level system
coupled to a harmonic oscillator. Our technique uses ultranarrowband composite pulses on …

Volume 54 of the Advances in Atomic, Molecular, and Optical Physics Series contains ten
contributions, covering a diversity of subject areas in atomic, molecular and optical physics …

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 present a single-shot method to measure motional states in the number basis. The
technique can be applied to systems with at least three nondegenerate energy levels which …

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 cross section of a given process fundamentally quantifies the probability for that process
to occur. In the quantum regime of low energies, the cross section can greatly vary with …

We report a precise determination of the lifetime of the (4 p) 2 P 3/2 state of Ca+ 40, τ P 3/2=
6.639 (42) ns, using a combination of measurements of the induced light shift and scattering …

Ultracold atom-ion collisions are an emerging field of research that can ultimately lead to
their precise quantum control. In collisions in which the ion is prepared in an excited state …
