معرفی
Ove Axner is a Professor at the Department of Physics, Umeå University, leading the Quantum Pascal Group. His research focuses on developing laser-based measurement techniques for ultra-sensitive detection of atoms and molecules in gas phase, particularly in analytical laser spectroscopy and refractometry. He has contributed to advancements in Fabry-Pérot cavity-based refractometry for precision pressure and density assessments, including collaborations with European national metrology institutes.
Key research areas include gas modulation refractometry (GAMOR), sub-Doppler double-resonance spectroscopy using frequency combs, and the realization of SI units (e.g., the pascal) via optical methods. His work emphasizes high-precision instrumentation, such as transportable refractometers and dual-cavity systems using Invar alloys for thermal stability.
Publications span high-impact journals like Nature Communications, Optics Letters, and Applied Spectroscopy, with a focus on cavity-enhanced spectroscopy, molecular transition analysis, and metrological applications. Current projects include the 'Quantum Molar Density' and 'Quantum Pascal' initiatives (2021–2024) aimed at advancing optical pressure standards and molar density measurements.
