Local, mm-scale H magnetic resonance imaging using atomic vapors
Sven Bodenstedt, Morgan W. Mitchell, Michael C. D. Tayler
We demonstrate a practical and sensitive low-field approach to magnetic resonance imaging (MRI) of L-scale samples using an optically pumped magnetometer (OPM). Using a simple…
Dynamics of hyperpolarized nuclear spins at Zeeman-insensitive points
James Eills, Anushka Singh, Amir-Mahyar Teimoori +3
Avoided crossing (LAC) transitions are central to spin-based precision measurements since they provide strong observability and field-perturbation insensitivity, but while observed…
Cyclicity of interaction frame transformations
Michael C D Tayler, Mohamed Sabba
We identify a cyclic property of rotation sequences involving piecewise displacements about arbitrary axes in three dimensions. Specifically, when transformation to the toggli…
Zero- to Ultralow-field Nuclear Magnetic Resonance
Danila A. Barskiy, John W. Blanchard, Dmitry Budker +5
Zero and ultralow-field nuclear magnetic resonance (ZULF NMR) is an NMR modality where experiments are performed in fields at which spin-spin interactions within molecules and mate…
Live magnetic observation of parahydrogen hyperpolarization dynamics
James Eills, Morgan W. Mitchell, Irene Marco Rius +1
Hyperpolarized nuclear spins in molecules exhibit high magnetization that is unachievable by classical polarization techniques, making them widely used as sensors in physics, chemi…
