Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and there exists a superfluid phase transition at a finite temperature. In thi

We dress atoms with multiple-radiofrequency (RF) fields and investigate the spectrum of transitions driven by an additional probe field. A complete theoretical description of this rich spectrum is presented, in which we find allowed transitions and d

This book is primarily intended to accompany an advanced undergraduate course in atomic physics. However, the elementary atomic physics covered in the early chapters should be accessible to undergraduates when they are first introduced to the subject
We have observed the 1S-2S transition in atomic hydrogen gas with a resolution of 5 parts in 109 by Doppler-free two-photon spectroscopy, using multimilliwatt cw radiation near 243 nm generated by sum-frequency mixing. The experiment opens the way to

We have measured the 1S-2S transition frequency in atomic hydrogen with a precision of 7 parts in 10/sup 10/ by continuous-wave Doppler-free two-photon spectroscopy. We employ cavity-enhanced multimilliwatt radiation near 243 nm produced by sum-frequ

The development of laser cooling has an important impact on many aspects of atomic physics and quantum optics. The efforts to understand the various types of force exerted on atoms by laser light have led to some interesting physics and it is now pos

This thesis describes the experimental realisation and characterisation of three non-trivial trapping geometries for ultracold atoms. The double-well, ring and to some degree shell trap are examples of a highly versatile class of traps called time-av

We report on fully quantum calculations of the momentum distribution of atoms cooled in the sigma +- sigma - configuration. These distributions have sharp quantum features at integer multiples of the photon momentum h(cross)k, similar to those which
