Quantum-assured magnetic navigation achieves positioning accuracy better than a strategic-grade INS in airborne and ground-based field trials
Murat Muradoglu, Mattias T. Johnsson, Nathanial M. Wilson +16
Modern navigation systems rely critically on GNSS, which in many cases is unavailable or unreliable (e.g. due to jamming or spoofing). For this reason there is great interest in au…
Application of interpretable machine learning for cross-diagnostic inference on the ST40 spherical tokamak
Tadas Pyragius, Cary Colgan, Hazel Lowe +4
Machine learning models are exceptionally effective in capturing complex non-linear relationships of high-dimensional datasets and making accurate predictions. However, their intri…
Stroboscopic microwave spectroscopy of Voigt based optically pumped magnetometers
Hans Marin Florez, Tadas Pyragius, Thomas Fernholz
We present results of stroboscopic microwave spectroscopy of radio-frequency dressed optically pumped magnetometer. Interaction between radio-frequency dressed atoms and a synchron…
Detection and characterisation of conductive objects using electromagnetic induction and a fluxgate magnetometer
Lucy Elson, Adil Meraki, Lucas M. Rushton +2
Eddy currents induced in electrically conductive objects can be used to locate metallic objects as well as to assess the properties of materials non-destructively without physical…
Unshielded portable optically pumped magnetometer for the remote detection of conductive objects using eddy current measurements
L. M. Rushton, T. Pyragius, A. Meraki +2
Electrically conductive objects can be detected using the principle of electromagnetic induction where a primary oscillating magnetic field induces eddy currents in the object, whi…
A high performance active noise control system for magnetic fields
Tadas Pyragius, Kasper Jensen
We present a system for active noise control (ANC) of environmental magnetic fields based on a Filtered-x Least Mean Squares (FxLMS) algorithm. The system consists of a sensor that…
Floquet description of Optically Pumped Magnetometers
Hans Marin Florez, Tadas Pyragius
We present theoretical description of Voigt and Faraday effect based optically pumped magnetometers using the Floquet expansion. Our analysis describes the spin-operator dynamics o…
A Voigt effect based 3D vector magnetometer
Tadas Pyragius, Hans Marin Florez, Thomas Fernholz
We describe a method to dispersively detect all three vector components of an external magnetic field using alkali atoms based on the Voigt effect. Our method relies on measuring t…
Dispersive detection of radio-frequency dressed states
Sindhu Jammi, Tadas Pyragius, Mark G. Bason +2
We introduce a method to dispersively detect alkali atoms in radio-frequency dressed states. In particular, we use dressed detection to measure populations and population differenc…
Developing and building an absorption imaging system for Ultracold Atoms
Tadas Pyragius
In this report I attempt to outline the process of developing and building an absorption imaging system capable of imaging ultracold atoms. In the theory section I will discuss the…
