The Doret group (Charlie & Da-Yeon) attended DAMOP 2023 in Spokane, Washington along with the Majumder group, presenting a poster on Timmy Chang’s recently completed isotope Ca+ King Plot.

After productive senior theses, Timmy Chang and Renee DePencier Pinero are headed on to their next great adventures!  Timmy, who completed measurements of the Ca+  732 nm transition isotope shifts, will be headed to Stanford for PhD in physics starting … Continue reading →

This year’s DAMOP wasn’t quite the experience we’ve all been used to, as the conference was fully virtual.  I have to say, I thought the APS did a superb job of getting everything organized, and by making registration free it … Continue reading →

Another year, another DAMOP.  With the present overlap of DAMOP’s schedule with Williams Senior Week we had another year with no present Williams students at the conference.  But, that didn’t stop Williams from being well represented: Prof. Doret’s lab presented … Continue reading →

After a lot of late nights by Prof. Doret and Felix Knollmann ’19, we’ve finally finished our 729 nm E2 transition isotope shift measurements.  Final data looks something like this prior to analyzing possible systematics: Details to come in a … Continue reading →

Trapping ions presents a bit of a conundrum for frequency stabilizing lasers: How does one lock a laser to a line in some ion when you can’t access that line without the laser already being locked to let you trap … Continue reading →

One of the challenges of working with trapped ions is that collisions between the trapped ions and any other atoms can lead to scrambling of information stored in the ions’ internal states, re-ordering of ions trapped in a chain, reactions … Continue reading →

Prof. Doret made his annual pilgrimage to the APS DAMOP conference, part of a smaller-than-usual contingent of Williams attendees due to Prof. Majumder being otherwise occupied as interim president of the college.  Along with Prof. Doret, this year’s group included … Continue reading →

After four years in the basement of the Bronfman Science Center, our lab is moving to the new South Science Building.  Making the move happen required a lot of labeling, disassembly, and packing, but everything is on its way over.  … Continue reading →
