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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents our work on developing and improving the techniques of trapping and cooling an ultra-cold cloud of Lithium-7 atoms and the realization of the Bose- Einstein condensate as a first step to study quantum magnetism in optical lattice. The techniques used in this experiment include Zeeman slowing, magneto-optical trapping (MOT), gray molasses, static magnetic trapping, evaporative cooling, optical dipole trapping (ODT), etc. The apparatus has the capability of creating a Bose-Einstein condensate with almost 106 atoms in 10 seconds as well as tuning the interaction between atoms in a BEC using the Feshbach resonance with a magnetic bias field of up to ~~ 1000G.

Book excerpt: This work describes the design and construction of the Bose-Einstein condensation (BEC) apparatus at the University of Toronto. The aim of the experiment is to create a Bose-Einstein condensate out of a vapour cloud of 87Rb atoms using a combination of laser cooling, magnetic trapping and evaporative cooling. The design and construction of all of the constituent parts necessary for the realization of these techniques are described in this work. The apparatus consists of two magneto-optical traps (MOTs, whereby the atoms are collected from a background vapour into the first MOT, and then transferred into the second MOT, which is in a region of ultra-high vacuum (

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is devoted to the construction, optimization and characterization of an experimental apparatus, capable of creating spinor condensates of ~1x10^5 atoms with a repetition rate of 10s, using an all-optical evaporation technique. I report a complete description of the experimental apparatus and techniques used in the experiment and a characterization of the BEC sample. We study the transmission of absorption imaging pictures through a coherent fiber bundle. We show that the fiber bundle introduces spurious noise in the picture mainly due to the strong core-to-core coupling. We demonstrate that we can retrieve exact quantitative information about the atomic system using this technique. We also explore the equilibration dynamics of ferromagnetic spin-1 system as a function of the initial magnetization of the sample and the external magnetic field. We show that the magnetization of the system is conserved despite of the presence of dissipative processes that are intrinsic to any experiment. We investigated the formation of the BEC in a spin-1 quantum gas in the presence of an external magnetic field. We report on the spontaneous magnetization of the condensate fraction during the evaporation process at low magnetic fields. We as well observe multi-step condensation, and found signatures of a possible interspecies Feshbach resonance.
