Abstract Optically Pumped Magnetometers (OPMs) have emerged as a viable and wearable
alternative to cryogenic, superconducting MEG systems. This new generation of sensors has …

Some of the most sensitive methods of measuring magnetic fields use interactions of
resonant light with atomic vapour. Recent developments in this vibrant field have led to …

We study experimentally the fundamental limits of sensitivity of an atomic radio-frequency
magnetometer. First, we apply an optimal sequence of state preparation, evolution, and the …

Alkali-metal magnetometers use the coherent precession of polarized atomic spins to detect
and measure magnetic fields. Recent advances have enabled magnetometers to become …

We discuss the basic physics and instrumentation issues related to high-performance
physical and inertial sensors based on atomic spectroscopy. Recent work on atomic …

Highly sensitive magnetometers capable of measuring magnetic fields below 1 pT have an
impact on areas as diverse as geophysical surveying, the detection of unexploded …

We report on the development of a microfabricated atomic magnetic gradiometer based on
optical spectroscopy of alkali atoms in the vapor phase. The gradiometer, which operates in …

Radio frequency (RF) magnetometers based on nitrogen vacancy centers in diamond are
predicted to offer femtotesla sensitivity, but previous experiments were limited to the …

The spectroscopy of hot atomic vapours is a hot topic. Many of the work-horse techniques of
contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic …
