Book Description
(Cont.) Partially condensed atomic vapors were confined by a combination of gravitational and magnetic forces. They were adiabatically decompressed, by weakening the gravito-magnetic trap to a mean frequency of 1 Hz, then evaporatively reduced in size to 2500 atoms. This lowered the peak condensate density to 5 x 1010 atoms/cm3 and cooled the entire cloud in all three dimensions to a kinetic temperature of 450±80 pK.

Book Description
A novel wire-based magneto-optical trap has been demonstrated which enables to collect up to 3x10^8 cold atoms close to the reflecting surface of an atom chip. These atoms are subsequently transferred to micro-traps generated by wires mounted on the atom chip and Bose-Einstein condensation has been achieved. The Bose-Einstein condensates (BECs) created in the micro-traps form in the one-dimensional Thomas-Fermi regime. The cross-over between three-dimensional and one-dimensional BECs has been investigated by monitoring the transverse size of the BEC after ballistic expansion. Good agreement to theory has been found. As an application, one-dimensional BECs have been used to implement a microscopic magnetic field sensor. This sensor enables field measurements in a region which is not accessible for today's state-of-the-art sensors. A field sensitivity of 4 nT at a spatial resolution of 3 micrometer has been demonstrated. To investigate the phase-properties of a one-dimensional BEC, coherent splitting of a one-dimensional BEC has been achieved and interferometry on an atom chip has been demonstrated.

Book Description
This stimulating discussion of a rapidly developing field is divided into two parts. The first features tutorials in textbook style providing self-contained introductions to the various areas relevant to atom chip research. Part II contains research reviews that provide an integrated account of the current state in an active area of research where atom chips are employed, and explore possible routes of future progress. Depending on the subject, the length of the review and the relative weight of the 'review' and 'outlook' parts vary, since the authors include their own personal view and style in their accounts.

Book Description
Nanoscale physics has become one of the rapidly developing areas of contemporary physics because of its direct relevance to newly emerging area, nanotechnologies. Nanoscale devices and quantum functional materials are usually constructed based on the results of fundamental studies on nanoscale physics. Therefore studying physical phenomena in nanosized systems is of importance for progressive development of nanotechnologies. In this context study of complex phenomena in such systems and using them for controlling purposes is of great practical importance. Namely, such studies are brought together in this book, which contains 27 papers on various aspects of nanoscale physics and nonlinear dynamics.

Book Description
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.
