Download or read book Bose-Einstein Condensates in Magnetic Double Well Potentials written by Thorsten Schumm and published by . This book was released on 2006 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents two realizations of magnetic double well potentials for Bose-Einstein condensates (BECs) on atom chips. One approach utilizes static magnetic traps, created by current carrying micro wires, manipulating the atoms close to the chip surface. As in all other atom chip experiments, cold atom clouds are found to break up to pieces in the vicinity of the trapping structure. A careful study of the underlying magnetic potential could attribute this fragmentation to current deviations, caused by corrugation of the wire edges. To avoid this effect, a new fabrication technique (electron beam lithography, gold evaporation) was employed to create 700nm cross section wires of significantly improved quality. A BEC was created and successfully transferred to the sub-micron structure, generating the double well. The general qualification of the device could be demonstrated by splitting cold thermal atomic clouds. However, numerous technical problems do yet prevent us from performing the experiment with BECs. The second approach pursued in this thesis combines static magnetic traps with oscillating (RF) magnetic fields and realizes a double well in the emerging adiabatic dressed potential. This scheme can be realized far from the chip surface, fragmentation does not occur and Bose-Einstein condensates could be split successfully. We realize a matter wave interferometer by recombining the two clouds in free expansion. The arising interference patterns reveal a narrow distribution of the relative phase, indicating a coherent splitting process. We monitor the phase evolution throughout and after the splitting and control it by deliberately unbalancing the double well.

This book was released on 2005-12-15 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the latest volume in the series of proceedings from the biannual International Conference on Laser Spectroscopy, one of the leading conferences in the field. Over its 34-year history, this conference series has been a forum for the announcement of many new developments in laser physics and laser spectroscopy and more recently laser cooling of atoms and quantum information processing. The proceedings include contributions from the invited speakers and a selection of contributed papers.A particular theme for this volume is precision measurements. Motivated by the untapped potential for vast improvements in accuracy offered by atomic systems, this subject has advanced tremendously in recent years by new developments in laser technology. This has been recognized by the 2005 Nobel Prize in Physics awarded to two of the pioneers in the field and contributors to these proceedings, J L Hall and T W Hänsch.The other main theme of the proceedings is cold atoms and quantum degenerate gases. This conference marked the 10th anniversary of the first announcement of an atomic Bose-Einstein Condensate at the 12th International Conference on Laser Spectroscopy with a contribution from Nobel Laureate Eric Cornell.

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.

Download or read book Bose-Einstein Condensation in Atomic Gases written by Società italiana di fisica and published by IOS Press. This book was released on 1999 with total page 664 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.

Download or read book A Bose-Einstein Condensate Coupled to a Micromechanical Oscillator written by David Hunger and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2010 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultracold neutral atoms can be trapped and coherently manipulated close to a surface using chip-based magnetic microtraps. This opens the possibility of studying interactions between atoms and on-chip solid-state systems such as micro- and nanostructured mechanical oscillators. This thesis reports experiments, where a controlled coupling between a Bose-Einstein condensate and a micromechanical oscillator is realized for the first time. The interaction relies on surface forces experienced by the atoms trapped at about 1 micrometer distance from the mechanical structure. The surface forces are used to resonantly couple the mechanical motion of the oscillator to collective motion of the atoms. Coupling via surface forces does not require magnets, electrodes, or mirrors on the oscillator and could thus be employed to couple atoms to molecular-scale oscillators such as carbon nanotubes. In the long-term, the toolbox for quantum manipulation of ultracold atoms could be employed to read out, cool, and coherently manipulate the quantum state of a mechanical oscillator. The thesis discusses three different scenarios that could enable atom-oscillator coupling at the quantum level.

This book was released on 2015-12-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis demonstrates a full Mach–Zehnder interferometer with interacting Bose–Einstein condensates confined on an atom chip. It relies on the coherent manipulation of atoms trapped in a magnetic double-well potential, for which the author developed a novel type of beam splitter. Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices, both for technological applications and fundamental tests. This requires the development of atom-optics analogues to beam splitters, phase shifters and recombiners. Particle interactions in the Bose–Einstein condensate lead to a nonlinearity, absent in photon optics. This is exploited to generate a non-classical state with reduced atom-number fluctuations inside the interferometer. This state is then used to study the interaction-induced dephasing of the quantum superposition. The resulting coherence times are found to be a factor of three longer than expected for coherent states, highlighting the potential of entanglement as a resource for quantum-enhanced metrology.
