This book was released on 2011 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of an apparatus capable of producing Bose-Einstein condensates marks a significant milestone in every experimental cold atom laboratory. In this thesis I describe the development of a system to create a Bose-Einstein condensate of 87RB in a Time-Orbiting Potential trap.I review the optical and magnetic techniques required to trap and cool an atomic sample under vacuum, motivating our decision to build a double MOT system comprised of a high-pressure (10-9 torr) chamber to gather atoms and a low-pressure (10-11 torr) chamber to cool atoms to degeneracy.By theoretically modeling the atom number and temperature inside the magnetic trap during evaporative cooling I demonstrate a simple approach to determining a cooling path that reaches the transition temperature. By making use of the condensates produced under these non-optimized conditions I determine the heating rate of the condensate in the TOP trap to be 300 nK/s. I further use the condensates to make a more precise measurement of the TOP trap bias field.I improve upon the conventional evaporation path used in TOP trap experiments by introducing and optimizing additional bias field compression stages in between RF evaporation ramps. I demonstrate how, by adding these additional stages, the system is capable of reaching the BEC phase transition with a final atom number of 2x 105. In contrast, RF evaporation after only a single bias field ramp has yielded condensates with only 30 x 103 atoms.

Book Synopsis Collected Papers of Carl Wieman by : Carl E. Wieman
Download or read book Collected Papers of Carl Wieman written by Carl E. Wieman and published by World Scientific. This book was released on 2008 with total page 827 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carl Wieman's contributions have had a major impact on defining the field of atomic physics as it exists today. His ground-breaking research has included precision laser spectroscopy; using lasers and atoms to provide important table-top tests of theories of elementary particle physics; the development of techniques to cool and trap atoms using laser light, particularly in inventing much simpler, less expensive ways to do this; the understanding of how atoms interact with one another and light at ultracold temperatures; and the creation of the first Bose-Einstein condensation in a dilute gas, and the study of the properties of this condensate. In recent years, he has also turned his attention to physics education and new methods and research in that area. This indispensable volume presents his collected papers, with annotations from the author, tracing his fascinating research path and providing valuable insight about the significance of the works.
Book Synopsis Bose-Einstein Condensation in a Robust Microtrap -- the Combination of Wire Traps and Atom Chips by :

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the presented work, we report about the successful creation of a Rubidium Bose-Einstein condensate. We use so called magnetic wire traps, which are especially simple, as they consist out of a wire and a homogeneous bias field. These wire traps are especially suited for Bose-Einstein condensation. Furthermore complex trapping potentials to manipulate a Bose-Einstein condensate can be realized. We combine 'large' and small scale wire traps. The 'large' scale is realized with a massive copper structure, while for the small wire traps we use the so called atom chip. This combination is promising, because it allowed us to develop a condensation process in the copper structure, which is independent of the structures on the atom chip, and thus the exchange of the 'physics' area. First experiments with the Bose-Einstein condensate are presented and discussed in detail.

Book Synopsis Bose-Einstein Condensation by : Keith Burnett (Ed); Mark Edwar
Download or read book Bose-Einstein Condensation written by Keith Burnett (Ed); Mark Edwar and published by DIANE Publishing. This book was released on 1996-12 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most remarkable effects that quantum mechanics adds to the catalog of the thermal properties of matter is "condensation" of an ideal gas of identical particles into a single quantum state, the principle of which was discovered in the theory of statistical mechanics by Bose and Einstein in the 1920s. Bose-Einstein condensation (BEC) is a mechanism for producing a macroscopic quantum system, and is exemplary of the macroscopic quantum phenomena of superconductivity and superfluidity.These 15 papers provide an introduction to current work on BEC.

Book Synopsis Condensazione Di Bose-Einstein Nei Gas Atomici by : M. Inguscio
Download or read book Condensazione Di Bose-Einstein Nei Gas Atomici written by M. Inguscio and published by IOS Press. This book was released on 1999 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although first proposed by Einstein in 1924, Bose-Einstein condensation (BEC) in a gas was not achieved until 1995 when, using a combination of laser cooling and trapping, and magnetic trapping and evaporation, it was first observed in rubidium and then in lithium and sodium, cooled down to extremely low temperatures. This book brought together many leaders in both theory and experiment on Bose-Einstein condensation in gases. Their lectures provided a detailed coverage of the experimental techniques for the creation and study of BEC, as well as the theoretical foundation for understanding the properties of this novel system. This volume provides the first systematic review of the field and the many developments that have taken place in the past three years.
