Investigating electromagnetically induced transparency spectral lineshape distortion due to non-uniform fields in Rydberg-atom electrometry Open
We investigate the effects of spatially non-uniform radio-frequency electric (E) field amplitudes on the spectral line shapes of electromagnetically induced transparency (EIT) signals in Rydberg atomic systems used in electrometry (i.e., t…

Rydberg state engineering: A comparison of tuning schemes for continuous frequency sensing Open
On-resonance Rydberg atom-based radio-frequency (RF) electric field sensing methods remain limited by the narrow frequency signal detection bands available by resonant transitions. The use of an additional RF tuner field to dress or shift …

Clean, robust alkali sources by intercalation within highly oriented pyrolytic graphite Open
We report the fabrication, characterization, and use of rubidium vapor dispensers based on highly oriented pyrolytic graphite (HOPG) intercalated with metallic rubidium. Compared to commercial chromate salt dispensers, these intercalated H…

Tunable axial potentials for atom-chip waveguides Open
We present a method for generating precise magnetic potentials that can be\ndescribed by a polynomial series along the axis of a cold atom waveguide near\nthe surface of an atom chip. With a single chip design consisting of several\nwire p…

Two-dimensional grating magneto-optical trap Open
We demonstrate a two-dimensional grating magneto optical trap (2D GMOT) with a single input beam and a planar diffraction grating in 87Rb. This configuration allows for an increase in experimental access when compared with a traditional 2D…

A Wigner Function Approach to Coherence in a Talbot-Lau Interferometer Open
Using a thermal gas, we model the signal of a trapped interferometer. This interferometer uses two short laser pulses, separated by time T, which act as a phase grating for the matter waves. Near time 2 T , there is an echo in the cloud’s …
