Nonzero-Order Resonances in Single-Beam Spin-Exchange Relaxation-Free Magnetometers

open access: yesPhotonics, 2023
Zero-field optically pumped magnetometers operating in the spin-exchange relaxation-free (SERF) regime have been extensively studied, and usually depend on zeroth-order parametric resonance to measure the magnetic field. However, the studies conducted on

A novel oven structure for improving temperature uniformity of vapor cell in atomic sensors

open access: yesResults in Physics, 2023
Alkali-metal vapor cells are key elements of atomic sensors. The temperature uniformity in the vapor cell is important for the sensitivity of the atomic sensors especially highly-sensitive SERF atomic magnetometers.

Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension [PDF]

open access: yes, 2009
Aims: We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations ...
