Description
The mystery of dark matter is one of modern physics' biggest puzzles.
Astrophysical evidence suggests that around 85% of the universe’s matter is "dark", yet we have never directly observed it, nor do we know its microscopic properties. Most dark matter experiments focus on WIMPs (weakly interacting massive particles), with masses ~ 10-1000 times that of a proton.
As WIMP searches continue to yield no results, interest is growing in exploring a wider range of possibilities. With the possible dark matter mass range spanning an astounding 90 orders of magnitude, extending dark matter searches beyond the WIMP paradigm requires entirely new and sensitive experimental strategies.
In this talk, I’ll discuss the compelling case for particle dark matter and explore some new approaches that leverage atomic phenomena to extend the dark matter search into lower mass ranges enlightening our search for dark matter, including taking advantage of the extraordinary precision of optical atomic clocks.
