Hyperpolarization-enabled cooperative molecular magnetic amplification
Jingyan Xu, Raphael Kircher, Min Jiang +3
Detecting weak magnetic fields at hertz frequencies is central to biomagnetism, geophysical sensing, and searches for new physics, yet it remains challenging because of technical s…
Chemically-polarized material for nuclear and particle physics
Benjamin G. Collins, Daniel P. Watts, Mikhail Bashkanov +6
Spin-polarized solid targets have underpinned many recent key advances in nuclear and particle physics, yet traditional methods to produce them face significant limitations due to…
Zero- to low-field J-spectroscopy with a diamond magnetometer
Muhib Omar, Jingyan Xu, Raphael Kircher +8
We report measurements of zero- to ultra-low-field nuclear magnetic resonance (ZULF NMR) signals at frequencies of a few hertz with a diamond-based magnetic sensor. The sensing dia…
Hyperpolarized Molecular Nuclear Spins Achieve Magnetic Amplification
Shengbang Zhou, Qing Li, Yi Ren +6
The use of nuclear spins as physical sensing systems is disadvantaged by their low signal responsivity, particularly when compared to sensing techniques based on electron spins. Th…
