Simultaneous cooling and trapping of 6Li and 85/87Rb
This thesis provides a summary of the laser system constructed in the Quantum Degenerate Gases Laboratory for laser cooling and trapping of 85/87Rband 6Li as well as of experiments that have been pursued in our lab to date. The first chapter provides an overview of the experimental focus of the QDG …

461nm laser for studies in ultracold neutral strontium
A 461 nm laser was constructed for the purposes of studying ultracold neutral strontium. The dipole-allowed 1 S0 → 1P1 transition at 460.862 nm can be used in laser cooling and trapping; optical imaging, Zeeman slowing, and photoassociative spectroscopy. We produce light at this wavelength by …

Bose-Fermi mixtures of ultracold gases of dysprosium
Laser cooling and trapping of the most magnetic fermionic atom, dysprosium (Dy), may provide a framework to explore quantum liquid crystal (QLC) theory (Chapter 1). This thesis presents details of the Dy laser cooling and trapping apparatus including the laser systems at 421, 741, and 1064 nm, the …

Progress Towards a Spinor Bose-Einstein Condensate Machine
Laser cooling and trapping of neutral particles has become a major area of research in atomic physics with the discovery of the first Bose-Einstein condensates (BECs) in 1995. These ultracold atomic vapors allow for study of fundamental quantum electromagnetic properties of atoms that are otherwise …

Probing nonlocal correlations with ultralong-range Rydberg molecules
… provide pristine environments for creating and manipulating strongly-interacting quantum systems. The flexibility and utility of ultracold atomic systems comes at the cost of isolation of the quantum system away from environmental perturbations inside of an ultra-high vacuum chamber. This …

Light Scattering in Ultracold High Density Rubidium Vapor
<p>Recent developments in laser cooling and trapping opened the door to a world full of new opportunities for research in atomic, molecular and optical physics as well as condensed matter physics. It became possible to do experiments under conditions that are hard to achieve in condensed matter …

A new apparatus for experiments with Caesium Bose-Einstein Condensates
This thesis reports on the design and construction of an experimental apparatus capable of generating Bose-Einstein condensates (BECs) of spin-polarised caesium-133 atoms. Caesium condensates offer excellent control over interatomic interactions due to the rich landscape of low-field magnetic …

Manipulation and control of ultra-cold rubidium atoms
… PhD an experimental set-up has been designed and implemented to confine neutral atoms in microscopic dipole traps and to manipulate their internal states by laser excitation to Rydberg states. A lot of effort was devoted to the stabilization of the laser sources for two-photon excitation to …

An atom trap trace analysis (ATTA) system for measuring ultra-low contamination by krypton in xenon dark matter detectors
… undergoes beta-decay with a 687 keV end point and 10.8 year halflife, which contributes background events and limits the sensitivity of the experiment. In order to achieve the desired sensitivity, the contamination by krypton is reduced to the part per trillion (ppt) level by cryogenic …

Nonlocal correlations between freely propagating pairs of atoms
… to opening up vibrant fields of research and enabling classically untenable technologies. Perhaps the most striking aspect of quantum mechanics is exhibited in the infamous Einstein-Podolsky-Rosen (EPR) paradox, as the violation of locality from distant entangled particles. Due to many …
