Adaptive multipole models of optically pumped magnetometer data. [PDF]
Hum Brain MappAbstractMultipole expansions have been used extensively in the Magnetoencephalography (MEG) literature for mitigating environmental interference and modelling brain signal. However, their application to Optically Pumped Magnetometer (OPM) data is challenging due to the wide variety of existing OPM sensor and array designs. We therefore explore how such

Ultra-sensitive Magnetic Microscopy with an Optically Pumped Magnetometer. [PDF]
Sci Rep, 2016 AbstractOptically pumped magnetometers (OPMs) based on lasers and alkali-metal vapor cells are currently the most sensitive non-cryogenic magnetic field sensors. Many applications in neuroscience and other fields require high-resolution, high-sensitivity magnetic microscopic measurements. In order to meet this demand we combined a cm-size spin-exchange

Floquet description of optically pumped magnetometers [PDF]
Physical Review A, 2021 We present theoretical description of Voigt and Faraday effect based optically pumped magnetometers using the Floquet expansion. Our analysis describes the spin-operator dynamics of the first, $\hat{F}(t)$, and second, $\hat{F}^2(t)$, order moments and takes into account of different pumping profiles and decoherence effects.

Peripheral Nerve Magnetoneurography with Optically Pumped Magnetometers [PDF]
Frontiers in Physiology, 2021 AbstractElectrodiagnosis is routinely integrated into clinical neurophysiology practice for peripheral nerve disease diagnoses such as neuropathy, demyelinating disorders, nerve entrapment/impingement, plexopathy or radiculopathy. Measured with conventional surface electrodes, the propagation of peripheral nerve action potentials along a nerve is the ...
