Photoassociation and Isotope shift spectroscopy with ultracold Strontium

POSTER

Abstract

Strontium makes an excellent candidate for studies in precision measurement and quantum simulation because of its ultra-narrow line used in atomic clocks and its many stable isotopes. We will present our recent measurement of photoassociation resonances near the $^1$S$_0$-$^3$P$_1$ intercombination line, as well as a recent measurement of the isotope shifts for both the $^1$S$_0$-$^3$P$_1$ and $^1$S$_0$-$^3$P$_0$ lines. For the photoassociation measurement, we have investigated the mass-scaling behavior of resonances relative to the $^3$P$_1$ state in bosonic strontium and measured a number of bound states for $^{84}$Sr and $^{86}$Sr. Isotope shifts were measured between all stable isotopes of strontium relative to $^{88}$Sr, allowing for a King Plot analysis. Finally, we will report on progress made in building a new ultracold strontium experiment. Improvements include implementing a Bitter coil design for the MOT, allowing us to achieve moderately high magnetic fields with easy and effective water cooling, and a newly designed vacuum chamber.
