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…
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…
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…
A high-flux cold-atom source utilising a grating atom chip
Hendrik Heine, Melanie S Le Gonidec, Aidan S Arnold +4
Bose-Einstein condensates (BECs) have been proposed for many applications in atom interferometry, as their coherence over long evolution times promises unprecedented sensitivity. T…
Single-beam grating-chip 3D and 1D optical lattices
Alan Bregazzi, James P. McGilligan, Paul F. Griffin +2
Ultracold atoms are crucial for unlocking truly precise and accurate quantum metrology, and provide an essential platform for quantum computing, communication and memories. One of…
An additive-manufactured microwave cavity for a compact cold-atom clock
Etienne Batori, Alan Bregazzi, Ben Lewis +4
We present an additive-manufactured microwave cavity for a Ramsey-type, double resonance, compact cold-atom clock. Atoms can be laser cooled inside the cavity using a grating magne…
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…
Demonstration of an inductively coupled ring trap for cold atoms
J. D. Pritchard, A. N. Dinkelaker, A. S. Arnold +2
We report the first demonstration of an inductively coupled magnetic ring trap for cold atoms. A uniform, ac magnetic field is used to induce current in a copper ring, which create…
Spatial interference from well-separated condensates
M. E. Zawadzki, P. F. Griffin, E. Riis +1
We use magnetic levitation and a variable-separation dual optical plug to obtain clear spatial interference between two condensates axially separated by up to 0.25 mm -- the larges…
A versatile and reliably re-usable ultrahigh vacuum viewport
K. J. Weatherill, J. D. Pritchard, C. S. Adams +3
We present a viewport for use in Ultra-high vacuum (UHV) based upon the preflattened solder seal design presented in earlier work, Cox et al. Rev. Sci. Inst. 74, 3185 (2003). The d…
