Cooling atomic ensembles with Maxwell's demon
This dissertation details the development and implementation of novel experimental techniques for cooling neutral atoms. Based on a method first proposed by Maxwell in a nineteenth century thought experiment, these techniques ...
Atom optics experiments in quantum chaos
Controlling atomic motion: from single particle classical mechanics to many body quantum dynamics
This dissertation covers a series of experiments designed to control atomic motion. The experiments progress from being completely classical in nature to being described by many-body quantum mechanical models. The first ...
Experiments with a Bose-Einstein condensate in a quasi-1D magnetic waveguide
This thesis is primarily a comprehensive discussion of the development of two experimental studies: the quantum transport and effects of heating of ultracold atoms. It specifically provides details of the manipulation ...
Coherent control of cold atoms in a[n] optical lattice
The dynamics of non-interacting, ultracold alkali atoms in the presence of counter-propagating lasers (optical lattice systems) is considered theoretically. The center of mass motion of an atom is such a system can be ...
Dynamic tunneling and chaos in atom optical systems
Dynamical tunneling has been observed in atom optics experiments by two groups, one in Texas using Cesium atoms and the other at NIST using a Bose–Einstein condensate. This tunneling is classically forbidden due to the ...
Dynamics of ultracold atoms in optical potentials
In this dissertation, we discuss the manipulation of ultracold atoms with optical fields. We show how a one-way barrier for ground state atoms may be constructed. Its use for phase space compression is analyzed. Using ...
Magnetic control of supersonic beams : magnetic slowing to isotope separation
General control of atoms and molecules has long been a goal for atomic physicists and physical chemists. Techniques such as laser cooling have been a huge breakthrough in studying ultra cold atoms and BECs. Although laser ...
