Kocharovskaya is a theorist (with supporting experiment) in coherent optics: EIT, lasing without inversion, and X-ray/gamma quantum optics using nuclear coherent control (Moessbauer nuclei) for ultra-narrowband photon storage and precision spectroscopy. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides coherent-control primitives relevant to precision sensing.
