November 5, 2019Shimon selected as 2019 Packard Fellow for Science and Engineering
Shimon is honored to have been selected as one of 22 members of the 2019 class of Packard Fellows for Science and Engineering. The fellowship, awarded to early-career scientists from across the U.S., provides $875,000 of …
October 16, 2019One isotope, two isotopes, three isotopes, four…
In the video linked to below, we trap and cool all four stable isotopes of strontium (88, 87, 86, and finally 84) in quick succession. (The delay between isotopes is purely for the purposes of …

Welcome to the Kolkowitz Lab! Our lab focuses on metrology, tests of fundamental physics, and nanoscale sensing using quantum systems.
In particular, we are building some of the most precise clocks in the world out of ultracold strontium atoms trapped in optical lattices. We are investigating ways to make these “optical lattice clocks” even more precise and accurate. We are also developing novel applications of these amazing instruments, including new tests of relativity, space-based gravitational wave detectors, and searches for dark matter and other physics beyond the Standard Model.
We are also researching new sensing techniques using single atom-scale defects trapped inside of diamonds. We are developing new protocols using spatial and temporal correlations between these defects to probe correlated dynamics in strongly interacting condensed matter systems. We are also investigating applications for new and under-explored defects in diamond and 2D materials.
