Book excerpt: Abstract: In this work we present the results of studies of one-dimensional (1D) and two-dimensional (2D) optical lattices on a chip. We have developed a method to create 1D and 2D optical lattices above an optical waveguide. The method is based on the destructive interference of the evanescent waves of two modes of the waveguide, resulting in a periodic array of nodes above the waveguide surface. For blue-detuned light, this constitutes an array of optical dipole traps for neutral atoms. One pair of modes coupled into a ridge waveguide creates a 1D array of nodes in this manner, and two orthogonal pairs of modes in a slab waveguide result in a 2D array of nodes. Computational analysis of our method showed that these optical atom chips may be suitable for use as a quantum register, and for studies of atom-surface interactions between the trapped atoms and the waveguide surface. Using realistic waveguide materials and laboratory laser parameters we found that for a laser power of [approx.]100 mW nodes can be created [approx.]100 nm above the waveguide surface. The nodes constitute atom traps that are [approx.]1mK deep, and have trap frequencies [approx.]1MHz and ground state sizes of [approx.]10 nm. The spacing between traps is [approx.]1 um enabling individual addressing with a focused laser beam. With the implementation of two-qubit gates in mind, initial investigations of extensions of the basic 2D optical lattice were conducted. Computational results for a counter-propagating 2D optical lattice with very close trap spacing ([approx.][lambda]/4) in one dimension, and for a 2D optical lattice with adjustable spacing between pairs of traps in one dimension are presented. An experimental setup for the realization of the proposed 2D optical lattices on a chip was designed and built. Several cooling and trapping steps necessary to prepare a cold atom sample for loading of the 2D optical lattice have been implemented successfully. In the course of previous studies of atom-surface interactions, a novel surface-ionization detector for 2D imaging of neutral atom samples was built and characterized. We find a detection efficiency [approx.]50 %, a spatial resolution of 20 um and a time response

Available in PDF, EPUB and Kindle. Book excerpt: Quantum phenomena of many-particle systems are fascinating in their complexity and are consequently not fully understood and largely untapped in terms of practical applications. Ultracold gases provide a unique platform to build up model systems of quantum many-body physics with highly controlled microscopic constituents. In this way, many-body quantum phenomena can be investigated with an unprecedented level of precision, and control and models that cannot be solved with present day computers may be studied using ultracold gases as a quantum simulator.This book addresses the need for a comprehensive description of the most important advanced experimental methods and techniques that have been developed along with the theoretical framework in a clear and applicable format. The focus is on methods that are especially crucial in probing and understanding the many-body nature of the quantum phenomena in ultracold gases and most topics are covered both from a theoretical and experimental viewpoint, with interrelated chapters written by experts from both sides of research.Graduate students and post-doctoral researches working on ultracold gases will benefit from this book, as well as researchers from other fields who wish to gain an overview of the recent fascinating developments in this very dynamically evolving field. Sufficient level of both detailed high level research and a pedagogical approach is maintained throughout the book so as to be of value to those entering the field as well as advanced researchers. Furthermore, both experimentalists and theorists will benefit from the book; close collaboration between the two are continuously driving the field to a very high level and will be strengthened to continue the important progress yet to be made in the field.
