October 2024: We are officially published!
Our paper on the electronic structure of AuC, AuSi, AuGe, AuSn, and AuPb has been published by Phys. Rev. A and is available here. Huge congratulations to Cooper Stuntz '24 and Kendall Rice '25 on their first paper! And we were so pleased to work on this project with our amazing collaborator Lan Cheng (Johns Hopkins).
This publication shows that these AuX molecules are extremely promising for precision measurements of the electron's electric dipole moment. We are currently working on the high-resolution spectroscopy of these molecules in our laboratory!
Also in October, honors thesis students Nicole Albright, Linden Niedeck, and Kendall Rice gave awesome poster presentations on their research projects! Ben is very excited to have such a great group of seniors working in the lab this year!
August 2024: That's a wrap on summer #2
Research assistants Kendall Rice '25 and Charlene Peng '26 finished off the summer with a great poster presentation. They were able to present on an amazingly productive summer, including the accomplishment of completing our molecular beam source and recording our first spectra!
About a week before the poster presentation, we made molecular beams of CaF to optimize our beam source and detection optics. I was blown away by the signal-to-noise ratio (>1000)! In the data on the right, the tiny blip at 494.502 THz comes from the rare isotopologue 44CaF. Nice work, Kendall and Charlene!
June 2024: Ephs at DAMOP!
We kicked off Summer 2024 at the annual DAMOP conference (in Fort Worth, TX this year). Former thesis student Cooper Stuntz presented a poster on Au-containing molecules that we suspect are promising candidates for electron EDM measurements. See the poster here!
As always, many Ephs attended DAMOP. (L-R): Justin Brown '05, Ashay Patel '18, Nathaniel Vilas '17, Ben, Josh Grossman '96, Cooper Stuntz '24, Charles Yang '24, John Lacy, and Nathan Schine '13. Julia Cline '15 was at DAMOP but couldn't be located for the photo :-(
May 2024: We're externally funded!
We just heard exciting news that we will receive an Undergraduate New Investigator grant from the American Chemical Society's Petroleum Research Fund (ACS PRF)!
This support will allow us to perform laser spectroscopy of nature's simplest gold-carbon bonds, in molecules such as AuC, AuCC, and AuCCH. These molecules are relevant to gold catalysis, hopefully providing insight into "greener" methods to synthesize important materials.
April 2024: Defense Day!
Cooper gave a great talk to cap off his senior honors thesis, sharing the exciting progress he made investigating the electronic structure of coinage metal carbides and building the molecular beam source that we will use to study these molecules. You can read more about this in Cooper's thesis, here.
Next up, Cooper is off to start a PhD in physical chemistry at Princeton University!

Stable laser alert!
Just before leaving to study abroad in Australia, Kendall Rice '25 got her laser-locking code up and running! Check out that automated detuning scan in action!
October 2023
Exciting day in lab: Nicole Albright '25 started to set up our new spectrometer and confirmed that white light can be dispersed into a rainbow! Seems like that Isaac Newton fellow was on to something...
Also: Augenbraun Lab members continue to show up in the Williams Record, including Kendall Rice '25 leading the Williams College Soccer Club to victory over Amherst(!!), and Phaedra Salerno '27 advocating for vegan options for the day's most important meal (dessert).

Let there be light... Cooper Stuntz '24 helped boot up our lab's first continuous-wave dye laser!
We wrapped up summer research with a poster session in Schow. Cooper and Kendall did an awesome job presenting their work on lasers, vacuum systems, and computational modeling!
Not shown is all the expertise they gained in dusting, organizing, and meteorology... I guess that breadth is just what makes working in a laser lab so fun!
July 2023
And we're in: we've placed our first dye laser on the optics table, signaling the start of work in the Augenbraun lab!
Very exciting to be starting this journey with research students Cooper Stuntz '24 and Kendall Rice '25! Cooper will also be working on a senior honors thesis in the lab during the coming academic year.
