Coherent transfer of the transverse momentum of an optical vortex beam to the motion of a single trapped ion
Felix Stopp, Maurizio Verde, Milton Katz +3
We demonstrate the excitation, using a structured light beam carrying orbital angular momentum, of the center of mass motion of a single atom in the transverse direction to the bea…
A Deterministic Single Ion Fountain
Felix Stopp, Henri Lehec, Ferdinand Schmidt-Kaler
We present an alternative approach for interconnecting trapped ion processor nodes by a deterministic single ion transfer out of the trap, into a free space trajectory, followed by…
Single Ion Thermal Wave Packet Analyzed Via Time-Of-Flight Detection
Felix Stopp, Luis Ortiz-Gutiérrez, Henri Lehec +1
A single Ca ion is confine in the harmonic potential of a Paul trap and cooled to a temperature of a few mK, with a wave packet of sub-m spatial and sub-m/s velocity uncerta…
Development of a recoil ion source providing slow Th ions including Th in a broad charge state distribution
Raphael Haas, Tom Kieck, Dmitry Budker +7
Ions of the isomer Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They…
Catching, trapping and in-situ-identification of thorium ions inside Coulomb crystals of Ca ions
Felix Stopp, Karin Groot-Berning, Georg Jacob +7
Thorium ions exhibit unique nuclear properties with high relevance for testing symmetries of nature, and Paul traps feature an ideal experimental platform for performing high preci…
Stern-Gerlach splitting of low-energy ion beams
Carsten Henkel, Georg Jacob, Felix Stopp +4
We present a feasibility study with several magnetic field configurations for creating spin-dependent forces that can split a low-energy ion beam by the Stern-Gerlach effect. To th…
Deterministic single ion implantation of rare-earth ions for nanometer resolution colour center generation
Karin Groot-Berning, Thomas Kornher, Georg Jacob +6
Single dopant atoms or dopant-related defect centers in a solid state matrix provide an attractive platform for quantum simulation of topological states, for quantum computing and…
Trapping and sympathetic cooling of single thorium ions for spectroscopy
Karin Groot-Berning, Felix Stopp, Georg Jacob +7
Precision optical spectroscopy of exotic ions reveals accurate information about nuclear properties such as charge radii and magnetic and quadrupole moments. Thorium ions exhibit u…
Spin and motion dynamics with zigzag ion crystals in transverse magnetic field gradients
J. Welzel, F. Stopp, F. Schmidt-Kaler
We investigate the dynamics of ion crystals in zigzag configuration in transverse magnetic field gradients. A surface-electrode Paul trap is employed to trap Ca ions and…
