Matter-wave collimation to picokelvin energies with scattering length and potential shape control

Alexander Herbst, Timothé Estrampes, Henning Albers +7

The sensitivity of atom interferometers depends on their ability to realize long pulse separation times and prevent loss of contrast by limiting the expansion of the atomic ensembl…

Long-distance chronometric leveling with a portable optical clock

J. Grotti, I. Nosske, S. B. Koller +19

We have measured the geopotential difference between two locations separated by by comparison of two optical lattice clocks via an interferometric fiber link, uti…

Optical stimulated-Raman sideband spectroscopy of a single Be ion in a Penning trap

J. M. Cornejo, J. Brombacher, J. -A. Coenders +5

We demonstrate optical sideband spectroscopy of a single Be ion in a cryogenic 5 Tesla Penning trap using two-photon stimulated-Raman transitions between the two Zeeman sub…

Heat transport in a Coulomb ion crystal with a topological defect

L. Timm, H. Weimer, L. Santos +1

The thermodynamics of low-dimensional systems departs significantly from phenomenologically deducted macroscopic laws. Particular examples, not yet fully understood, are provided b…

Cold highly charged ions in a radio-frequency trap with superconducting magnetic shielding

Elwin A. Dijck, Christian Warnecke, Malte Wehrheim +12

We implement sympathetic cooling of highly charged ions (HCI) by fully enclosing a linear Paul trap within a superconducting radio-frequency resonator. A quantization magnetic fiel…

How to Build an Optical Filter with an Atomic Vapor Cell

Denis Uhland, Helena Dillmann, Yijun Wang +1

The nature of atomic vapors, their natural alignment with interatomic transitions, and their ease of use make them highly suited for spectrally narrow-banded optical filters. Atomi…
