Atom-optics knife-edge: Measuring narrow momentum distributions
Ramón Ramos, David Spierings, Shreyas Potnis +1
By employing the equivalent of a knife-edge measurement for matter-waves, we are able to characterize ultra-low momentum widths. We measure a momentum width corresponding to an eff…

Laser frequency stabilization using a transfer interferometer
Shira Jackson, Hiromitsu Sawaoka, Nishant Bhatt +2
We present a laser frequency stabilization system that uses a transfer interferometer to stabilize slave lasers to a reference laser. Our implementation uses off-the-shelf optical…

Macroscopic Quantum Tunneling Escape of Bose-Einstein Condensates
Xinxin Zhao, Diego A. Alcala, Marie A. McLain +5
Recent experiments on macroscopic quantum tunneling reveal a non-exponential decay of the number of atoms trapped in a quasibound state behind a potential barrier. Through both exp…
