AC Sensing of NV Centers under Hydrostatic Pressure*

Nitrogen-vacancy color centers in diamond have attracted broad attention as quantum sensors for both static and dynamic magnetic, electrical, strain and thermal fields, and are particularly attractive for quantum sensing under pressure in diamond anvil cells. Optically-based nuclear magnetic resonance may be possible at pressures greater than a few GPa, and offers an attractive alternative to conventional Faraday-induction based detection. In this talk, we will discuss AC sensing of NV Centers under hydrostatic pressure inside of a diamond anvil cell, with a focus on technical challenges of performing these measurements.
