Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition
whose observation would have fundamental implications for neutrino physics, theories …

This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

Improved control of the motional and internal quantum states of ultracold neutral atoms and
ions has opened intriguing possibilities for quantum simulation and quantum computation …

We present, and derive analytic expressions for, a fundamental limit to the sympathetic
cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work …

Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a
single ion in a radio frequency ion trap. The distributions have power-law tails whose …

The gas-phase fluorescence excitation, emission and photodissociation characteristics of
three xanthene dyes (rhodamine 575, rhodamine 590, and rhodamine 6G) have been …

A hybrid ion-neutral trap provides an ideal system to study collisional dynamics between
ions and neutral atoms. This system provides a general cooling method that can be applied …

The immersion of a single ion confined by a radiofrequency (RF) trap in an ultracold atomic
gas extends the concept of buffer gas cooling to a new temperature regime. The steady-state …

An RF ion-funnel technique has been developed to extract ions from a high-pressure (10
bar) noble-gas environment into a vacuum (10− 6 mbar). Detailed simulations have been …

We present high-level ab initio potential energy curves for barium cations and dications
interacting with RG atoms (RG= rare gas)⁠. These potentials are employed to derive …
