Technique - (2) Spin noise spectroscopy in atomic vapors

Type: Experimental

Description:

Department(s)/lab(s): Physics | LuMIn - Lasers, Atomic & Quantum Optics (Bretenaker/Goldfarb) @ ENSPS
Summary:

Bretenaker (former LuMIn director) works on laser physics and quantum optics: sub-shot-noise sensing with phase-sensitive-amplifier-generated entangled beams, spin-noise spectroscopy in atomic vapours, EIT slow light, and quantum-limited passive resonant (fiber/bulk) gyroscopes with Thales. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work represents the fundamental-light and quantum-limited-rotation-sensing side.

Summary:

Goldfarb studies coherent effects in atomic vapours - EIT and slow light, spin-noise spectroscopy of spin-environment interaction, and EIT-based Rydberg-atom radio-frequency field sensing (electrometry) in warm cells. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work adds atomic-vapour electrometry and coherence spectroscopy.
