This article is designed as a step-by-step guide to optically pumped magnetometers based
on alkali atomic vapor cells. We begin with a general introduction to atomic magneto-optical …

We study the effect of optical polarization squeezing on the performance of a sensitive,
quantum-noise-limited optically pumped magnetometer. We use Bell-Bloom (BB) optical …

We describe a magnetic gradiometer that operates at finite fields and uses an intense
pulsed laser to polarize a 87 Rb atomic ensemble and a compact vertical-cavity surface …

We present a portable optically pumped magnetometer instrument for ultrasensitive
measurements within the Earth's magnetic field. The central part of the system is a sensor …

Under ideal conditions, quantum metrology promises a precision gain over classical
techniques scaling quadratically with the number of probe particles. At the same time, no-go …

We address the estimation of the magnetic field B acting on an ensemble of atoms with total
spin J subjected to collective transverse noise. By preparing an initial spin coherent state, for …

We report quantum enhancement of Faraday rotation spin noise spectroscopy by
polarization squeezing of the probe beam. Using natural abundance Rb in 100 Torr of N 2 …

The ground-state Hanle effect (GSHE) in alkali-metal atomic vapor using a single circularly
polarized light wave underlies one of the most reliable and simple techniques of modern …

We report on a single-channel rubidium radio-frequency atomic magnetometer operating in
unshielded environments and near room temperature with a measured sensitivity of 130 …

Contemporary understanding of correlations in quantum many-body systems and in
quantum phase transitions is based to a large extent on the recent intensive studies of …
