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 various pulse sequences including double quantum Ramsey and Echo, and how hydrostatic pressure affects the behavior of the NV Center.
