Field validation of GNSS-independent positioning enhancement using a wearable ultra-stable quantum magnetometer
Stirling Scholes, Dominic Hunter, Courtney Dyer +8
Increasing the resilience of positioning systems that currently rely on Global Navigation Satellite System (GNSS) signals can be achieved by incorporating stable and sensitive meas…
Fresnel zone plates for reconfigurable atomic waveguides
A. M. Pike, A. Dorne, L. Pickering +7
Fresnel zone plates (FZPs), with patterns of m resolution, allow the formation of clean, diffraction-limited foci -- but have a static phase profile. Spatial light modulators…
Rapid axial loading of a grating MOT with a cold-atom beam
Rachel Cannon, Aidan S. Arnold, Paul F. Griffin +2
Laser-cooled atoms are increasingly being used to realise practical quantum devices, motivating the development of compact and robust atom sources. Grating magneto-optical traps (g…
Intrinsic atomic calibration of oscillating magnetic fields in ULF and VLF bands
Zak Johnston, Paul F. Griffin, Erling Riis +3
We present a method for absolute calibration of received radio-frequency in the ultra low frequency (ULF), and very low frequency (VLF) range. This is achieved with the use of a ra…
High-Resolution Atomic Magnetometer-Based Imaging of Integrated Circuits and Batteries
Dominic Hunter, Marcin S. Mrozowski, Stuart J. Ingleby +7
Optically pumped magnetometers (OPMs) have emerged as a powerful technique for high-resolution magnetic field imaging. However, achieving sub-millimeter spatial resolution at sub-p…
Practical primary thermometry via alkali-metal-vapour Doppler broadening
Nicola Agnew, Veronika Vohníková, Erling Riis +2
Doppler-broadening thermometry (DBT) can be used as a calibration-free primary reference suitable for practical applications, e.g. reliably measuring temperatures over long periods…
A triaxial vectorization technique for a single-beam zero-field atomic magnetometer to suppress cross-axis projection error
Rach Dawson, Marcin S. Mrozowski, Dominic Hunter +4
Zero-field optically pumped magnetometers (OPMs) have emerged as an important technology for biomagnetism due to their ulta-sensitive performance, contained within a non-cryogenic…
Distributed network of optically pumped magnetometers for space weather monitoring
M. S. Mrozowski, A. S. Bell, P. F. Griffin +6
Spatial variation in the intensity of magnetospheric and ionospheric fluctuation during solar storms creates ground-induced currents, of importance in both infrastructure engineeri…
Free-induction-decay magnetic field imaging with a microfabricated Cs vapor cell
D. Hunter, C. Perrella, A. McWilliam +7
Magnetic field imaging is a valuable resource for signal source localization and characterization. This work reports an optically pumped magnetometer (OPM) based on the free-induct…
Single-laser, one beam, tetrahedral magneto-optical trap
Matthieu Vangeleyn, Paul F. Griffin, Erling Riis +1
We have realised a 4-beam pyramidal magneto-optical trap ideally suited for future microfabrication. Three mirrors split and steer a single incoming beam into a tripod of reflected…
