After 5.5 fun and productive years in the Physics Department at the University of Wisconsin – Madison, the Kolkowitz Lab has moved to a new home at UC Berkeley!
While I’m quite sad to leave UW – Madison and the wonderful physics community there, I’m also very excited about this new chapter for me and my research group. You can find the new Kolkowitz Lab webpage at: https://physics.berkeley.edu/research-faculty/kolkowitz-lab
Congratulations to Xin, Jack, Hong Ming, and Matt on the publication of their paper “A lab-based test of the gravitational redshift with a miniature clock network” in Nature Communications! You can read the entire published paper at this link (with no paywall or special access required): https://rdcu.be/djkVc.
In this paper, we experimentally confirm that time passes more slowly for a clock that is just 2.5 millimeters higher off the ground than another otherwise identical clock, as predicted by Einstein’s theory of general relativity. Observing this effect and confirming that it is there required comparing to clocks at 19 digits of precision and accuracy!
Congratulations to Dr. Aedan Gardill, who successfully defended his PhD today! His thesis is entitled: “Nanoscale metrology using the spin and charge states of single nitrogen vacancy centers in diamond.” Aedan will now move on from the Kolkowitz group to start a new position as a Product Development and Sales Engineer at Mad City Labs.
