Alkaline-earth atoms in optical tweezers

A Cooper, JP Covey, IS Madjarov, SG Porsev… - Physical Review X, 2018 - APS
We demonstrate single-shot imaging and narrow-line cooling of individual alkaline-earth
atoms in optical tweezers; specifically, strontium trapped in 515.2-nm light. Our approach …

Observation of Feshbach resonances between a single ion and ultracold atoms

P Weckesser, F Thielemann, D Wiater… - Nature, 2021 - nature.com
The control of physical systems and their dynamics on the level of individual quanta
underpins both fundamental science and quantum technologies. Trapped atomic and …

[HTML][HTML] The physics and applications of strongly coupled Coulomb systems (plasmas) levitated in electrodynamic traps

BM Mihalcea, VS Filinov, RA Syrovatka, LM Vasilyak - Physics reports, 2023 - Elsevier
Charged microparticles confined in electrodynamic traps evolve into strongly coupled
Coulomb systems (SCCS) which are the subject of current investigation. Recent results with …

Optical traps for sympathetic cooling of ions with ultracold neutral atoms

J Schmidt, P Weckesser, F Thielemann, T Schaetz… - Physical review …, 2020 - APS
We report the trapping of ultracold neutral Rb atoms and Ba+ ions in a common optical
potential in absence of any radio frequency (rf) fields. We prepare Ba+ at 370 μ K and …

Collective dynamics and defect generation for Wigner crystal ratchets

C Reichhardt, CJO Reichhardt - Physical Review B, 2023 - APS
We consider a two-dimensional Wigner crystal coupled to a quasi-one-dimensional
asymmetric potential under ac or dc driving. As a function of electron density, substrate …

Manipulating phonons of a trapped-ion system using optical tweezers

YH Teoh, M Sajjan, Z Sun, F Rajabi, R Islam - Physical Review A, 2021 - APS
We propose an experimental architecture where an array of optical tweezers affords site-
dependent control over the confining potential of a conventional radio-frequency ion trap …

Towards storage rings as quantum computers

KA Brown, T Roser - Physical Review Accelerators and Beams, 2020 - APS
We explore the possible use of particle beam storage rings as quantum computers. More
precisely, we consider creating an ion trap system, in which the same computational basis …

Trapping ion coulomb crystals in an optical lattice

D Hoenig, F Thielemann, L Karpa, T Walker… - Physical Review Letters, 2024 - APS
We report the optical trapping of multiple ions localized at individual lattice sites of a one-
dimensional optical lattice. We observe a fivefold increased range of axial dc-electric field …

Trapping, shaping, and isolating of an ion Coulomb crystal via state-selective optical potentials

P Weckesser, F Thielemann, D Hoenig, A Lambrecht… - Physical Review A, 2021 - APS
For conventional ion traps, the trapping potential is close to independent of the electronic
state, providing confinement for ions dependent primarily on their charge-to-mass ratio Q/m …
