Spin Squeezing for CASPEr Electric

This event is part of the Graduate Student Council Events.

Part of the student seminar series. A recording will be posted on the event page.

Abstract: The Heisenberg uncertainty principle sets a noise floor, known as the standard quantum limit, in many high-precision measurements such as atomic magnetometry and NMR. This limit can be circumvented by preparing the probes in spin-squeezed states which reduce the variance in the measured observable at the cost of increasing the variance in a conjugate observable. In this talk, I will introduce spin-squeezed states and explore possible ways they might be generated in the CASPEr-electric experiment, a high-precision NMR experiment searching for axions and axion like particles.
