Atomic Magnetometry Employing Vector Light Beams — •Riaan Philipp Schmidt1,2, Richard Aguiar Maduro4, Anton Peshkov1,2, Sonja Franke-Arnold4, and Andrey Surzhykov1,2,3 — 1PTB Braunschweig, Germany — 2TU Braunschweig, Germany — 3LENA Braunschweig, Germany — 4University of Glasgow, UK
During recent years, interest has been rising for applications of vector light beams toward magnetic field sensing. In particular, a series of experiments were performed to extract information about properties of static homogeneous magnetic fields from absorption profiles of vector light passing through an atomic gas target [1].
The talk will follow two directions. First, it will discuss an extension to the method described in Ref. [1] for oscillating homogeneous magnetic fields and static inhomogeneous magnetic fields. Second, we will discuss theoretical and experimental developments on Doppler-free polarization spectroscopy experiments including vector beams. These experiments open up new opportunities for the application of vector light in atomic magnetometry with warm atomic vapors, while experiments from Ref. [1] require temperatures in the sub-mK regime.
