Title of Talk:

*/"Ultracold Rubidium and Potassium System for Atom Chip-based Microwave 
and RF Potentials"/*

*Abstract:*In this 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.

*Bio:*Austin R. 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.

Open to the public.
