Available in PDF, EPUB and Kindle. Book excerpt: Annotation Physics researchers survey the methods used to produce, manipulate, and study the condensate in dilute atomic gases, which have generated a lot of excitement since their experimental demonstration in 1995. They emphasize the anticipated development of new types of sources for the novel macroscopic quantum system of coherent atoms. Such sources are looking more and more similar to the various types of lasers--pulsed, CW, mode locked--and likely to produce a revolution similar to that sparked by lasers four decades previously. The 23 papers comprise the proceedings of an international school of quantum electronics held in Erice, Italy in October 1999. Annotation c. Book News, Inc., Portland, OR (booknews.com).

This book was released on 2000-02-28 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bose-Einstein condensation of excitons is a unique effect in which the electronic states of a solid can self-organize to acquire quantum phase coherence. The phenomenon is closely linked to Bose-Einstein condensation in other systems such as liquid helium and laser-cooled atomic gases. This is the first book to provide a comprehensive survey of this field, covering theoretical aspects as well as recent experimental work. After setting out the relevant basic physics of excitons, the authors discuss exciton-phonon interactions as well as the behaviour of biexcitons. They cover exciton phase transitions and give particular attention to nonlinear optical effects including the optical Stark effect and chaos in excitonic systems. The thermodynamics of equilibrium, quasi-equilibrium, and nonequilibrium systems are examined in detail. The authors interweave theoretical and experimental results throughout the book, and it will be of great interest to graduate students and researchers in semiconductor and superconductor physics, quantum optics, and atomic physics.

Available in PDF, EPUB and Kindle. Book excerpt: This work reports on the construction of a new-generation system capable to create single-mode spinor Bose-Einstein condensates of 87Rb, and non-destructively probe them using optical Faraday rotation. This system brings together many of the stateof-the-art technologies in ultra-cold physics in a minimalist design which was possible due to the prolific advances in the field respect to the pioneering experiments (Cornell's, Ketterle's, and Chapman's groups). There is rich phenomena that can be potentially studied in this system from the study of predicted novel quantum phases and topologies to entanglement and spin squeezing which are useful for quantum information and interferometry. The potential of this system make it suitable to answer fundamental questions on the phase transition to a condensed and ferromagnetic state. In particular, this work describes theoretically and experimentally, the atomic spin coherence, which is relevant for applications like coherent sensing of magnetic fields. In this direction, our findings demonstrate the characteristics of our system make it a sensor with the best predicted energy resolution per unit bandwidth (̃10̂-2 h) among all the different technologies applied to magnetometry. The thesis is structured as follows: Part I is dedicated to the mathematical description of the relevant interactions. First, the interaction of optical polarization and atomic spin polarization is reviewed, with special attention to ac-Stark shifts, which are used to generate a conservative trapping potential and Faraday rotation effects that are used for non-destructive spin detection. Second, the interaction of the atoms with a magnetic field is presented. And finally, the mean-filed theory of spinor Bose-Einstein condensation is summarized. The dynamics of a spin-1system in this picture is described by a three-component Gross-Pitaevskii equation. Part II contains three chapters describing the implemented technologies and techniques used in the experiment to create and characterize a spinor condensate. The first chapter describes the ultrahigh vacuum, magnetic fields, lasers, spectroscopy and imaging needed to create a magneto optical trap (MOT) and transfer those atoms into an optical dipole trap (ODT). We implemented a non-standard loading technique based on the semicompensation of the strong differential lightshift induced by the ODT which profits from the effective dark-MOT created at the trap position. In the second chapter we detail, theoretically and experimentally, the all-optical evaporation process employed to achieve condensation in less than five second after the loading. In the final chapter the spin manipulation and read-out techniques are presented. Because there is no observable associated to the spin angle, we exploit the Faraday rotation effect and Stern-Gerlach imaging in order to retrieve information about the spin dynamics. Finally in Part III, we consider the potential of a spinor BEC as a magnetic sensor. The measurement of fundamental properties defining the sensitivity of the sensor are detailed. Those properties are the volume, the temporal coherence and the readout noise. We present a model of the magnetic field environment and its repercussion on the noise of the magnetometer. In the last chapter we present our perspectives to the possible applications of our system.

Available in PDF, EPUB and Kindle. Book excerpt: Using the time-splitting spectral method, the time- dependent GPE is discretized further more and different forms of potentials are used to obtain interesting results for trapping in harmonic and different potentials, confined in this work. Spatial and time discretization error analyses for present results were compared with those obtained by other authors for different techniques. Fourth- order time-splitting pseudospectral (TSP), Hermite pseudospectral (HP), Laguerre pseudospectral (LP) and Laguerre-Hermite pseudospectral (LHP) methods are improved which are developed to study GPE of rotating BEC. In all cases the characteristic feature of vortex dynamics and interactions in superconductivity and superfluidity are studied by considering the Ginzburg-Landau-Schrödinger equation (GLSE).Finally, to describe the dynamics of atom laser, the interaction Hamiltonian is derived between the two-level atoms with an electromagnetic field and then introducing the equations of motion. This interaction Hamiltonian is used to describe the outcoupling process in a Raman atom laser.
