Dynamic polarizabilities of cesium Rydberg states, explicitly n S 1/2, n P 1/2, n P 3/2, n D 3/2,
and n D 5/2, where the principal quantum number n is 40–70, are presented for linearly …

The relativistic configuration interaction plus many-body perturbation (RCI+ MBPT) method
is utilized to calculate the wave functions, energy levels, and reduced E 1 transition matrix …

We present measurements of three distinctive state-dependent wavelengths for the S 0 1-P
0 3 clock transition in 174 Yb atoms. Specifically, we determine two magic wavelengths at …

We report on the transport of a thermal cloud of ultracold cesium and rubidium atoms over
about 37 cm in under 25 ms using an optical conveyor belt formed by two …

We report on the transport of ultracold cesium and rubidium atoms over $37.2\, $ cm in
under $25\, $ ms using an optical conveyor belt formed by two counter-propagating beams …

Precise state-dependent control of optical potentials is of great importance for various
applications utilizing cold neutral atoms. In particular, tune-out wavelengths for the clock …

We present the experimental apparatus enabling the observation of the heteronuclear
Efimov effect in an optically trapped ultracold mixture of 6 Li-133 Cs with high-resolution …

The thesis deals with the experimental study of dilute ultracold gases of Cs-133 atoms mixed
with a degenerate Fermi Sea of Li-6 atoms. It focuses on the problem of the coupling of an …

Ultracold atoms in optical lattices allow the study of large ensembles of strongly interacting
quantum particles in an isolated environment. They are widely used as analogue quantum …

In this thesis the fast and efficient transport of Caesium and Rubidium atoms using an optical
conveyor-belt is presented. Up to $7\times 10^{7} $ atoms of either species can be …
