Programmable System on Chip for controlling an atomic physics experiment
A. Sitaram, G. K. Campbell, A. Restelli
Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well…
Isotope-shift spectroscopy of the and transitions in strontium
Hirokazu Miyake, Neal C. Pisenti, Peter K. Elgee +2
Isotope shift spectroscopy with narrow optical transitions provides a benchmark for atomic structure calculations and has also been proposed as a way to constrain theories predicti…
Narrow-line photoassociation spectroscopy and mass-scaling of bosonic strontium
B. J. Reschovsky, B. P. Ruzic, H. Miyake +3
Using new experimental measurements of photoassociation resonances near the intercombination transition in Sr and $^{8…
A rapidly expanding Bose-Einstein condensate: an expanding universe in the lab
S. Eckel, A. Kumar, T. Jacobson +2
We study the dynamics of a supersonically expanding ring-shaped Bose-Einstein condensate both experimentally and theoretically. The expansion redshifts long-wavelength excitations,…
An ultra-low noise, high-voltage piezo driver
N. C. Pisenti, A. Restelli, B. J. Reschovsky +2
We present an ultra-low noise, high-voltage driver suited for use with piezoelectric actuators and other low-current applications. The architecture uses a flyback switching regulat…
Temperature induced decay of persistent currents in a superfluid ultracold gas
Avinash Kumar, Stephen Eckel, Fred Jendrzejewski +1
We study how temperature affects the lifetime of a quantized, persistent current state in a toroidal Bose-Einstein condensate (BEC). When the temperature is increased, we find a de…
