Cold Rydberg atoms exposed to strong magnetic fields possess unique properties which
open the pathway for an intriguing many-body dynamics taking place in Rydberg gases …

We explore properties of atoms whose magnetic hyperfine sublevels are coupled by an
external magnetic radio frequency (rf) field. We perform a thorough theoretical analysis of …

Atom chips are a promising candidate for a scalable architecture for quantum information
processing provided a universal set of gates can be implemented with high fidelity. The …

We investigate the possibility of trapping ultracold Rb 87 atoms near the outside of a metallic
carbon nanotube, which we imagine using as a miniaturized current-carrying wire. We …

We discuss the properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap being
commonly used in ultracold atomic physics experiments. The Hamiltonian is derived, and it …

The quantum resonances of an atom possessing a single valence electron which shows
hyperfine interaction with the nucleus is investigated in the presence of a three-dimensional …

Atom waveguides are used to manipulate cold atoms in atom interferometers. The creation
of atom interferometers using cold atoms in miniature magnetic waveguides is one of many …

Subject of this thesis is the investigation of the quantum dynamics of ultracold atoms in
confined geometries. We discuss the behavior of ground state atoms inside a 3D magnetic …
