</span><span style="font-size:12.0pt;font-family:"Times

dissertation we study the development of microwave and RF
near-field potentials for use with atom chip trapped atomic
gases. These potentials are inherently spin-dependent, able
to target individual spin states simultaneously. In
contrast with traditional atom chip potentials, these RF
traps can be operated at arbitrary bias magnetic field
strengths and thus be combined with magnetic Feshbach
resonances. Furthermore, these potentials can strongly
suppress the potential roughness that plagues traditional
atom chip potentials. We present a dual chamber atom chip
apparatus for generating ultracold 87Rb and 39K atomic
gases. The apparatus produces quasi-pure Bose-Einstein
condensates of 104 87 Rb atoms in an atom chip trap that
features a dimple and good optical access. We have also
demonstrated production of ultracold 39K and subsequent
loading into the chip trap. We describe the details of the
dual chamber vacuum system, the cooling lasers, the magnetic
trap, the multi coil magnetic transport system, and the atom
chip. The apparatus is well suited for studies of
atom-surface forces, quantum pumping and transport
experiments, atom interferometry, novel chip-based traps,
and studies of one-dimensional many-body systems.</span><span

Ziltz was born on the 30th of April, 1986 in Harrisburg,
Pennsylvania. He attended West Hanover Elementary School,
Central Dauphin East Junior High and Central Dauphin High
School. After being inadvertently electrocuted several
times during his youth, he eventually found a passion for
physics. In 2004, he entered Bucknell University. He
graduated with honors in 2008 with a Bachelor of Science in
Physics and a minor in Mathematics. Austin entered the
College of William & Mary in the fall of 2008, and began
work with Dr. Seth Aubin in the Ultracold Atoms Group to
develop microwave and RF atom chip potentials and the
apparatus with which to study them. He received a Master of
Science in 2010. Austin began working for Laser &
Plasma Technologies in Hampton, Virginia in October 2014,
developing corrosion detection instruments for the Navy.</span><span
