Fast thermometry for trapped ions using dark resonances
Johannes Roßnagel, Karl Nicolas Tolazzi, Ferdinand Schmidt-Kaler +1
We experimentally demonstrate a method to determine the temperature of trapped ions which is suitable for monitoring fast thermalization processes. We show that observing and analy…
Two-dimensional spectroscopy for the study of ion Coulomb crystals
A. Lemmer, C. Cormick, C. T. Schmiegelow +2
Ion Coulomb crystals are currently establishing themselves as a highly controllable test-bed for mesoscopic systems of statistical mechanics. The detailed experimental interrogatio…
Generalised Kronig-Penney model for ultracold atomic quantum systems
A. Negretti, R. Gerritsma, Z. Idziaszek +2
We study the properties of a quantum particle interacting with a one dimensional structure of equidistant scattering centres. We derive an analytical expression for the dispersion…
Single particle microscopy with nanometer resolution
Georg Jacob, Karin Groot-Berning, Sebastian Wolf +5
We experimentally demonstrate nanoscopic transmission microscopy relying on a deterministic single particle source. This increases the signal-to-noise ratio with respect to convent…
Experimental realization of fast ion separation in segmented Paul traps
Thomas Ruster, Claudia Warschburger, Henning Kaufmann +7
We experimentally demonstrate fast separation of a two-ion crystal in a microstructured segmented Paul trap. By the use of spectroscopic calibration routines for the electrostatic…
Fast shuttling of a trapped ion in the presence of noise
Xiao-Jing Lu, J. G. Muga, Xi Chen +3
We theoretically investigate the motional excitation of a single ion caused by spring-constant and position uctuations of a harmonic trap during trap shuttling processes. A detaile…
