报告人介绍

Zhipan Wang is a PhD candidate at University of California, Davis. He earned his B.S. from the University of Science and Technology of China and worked as a researcher in Curro NMR lab in UC Davis.His research focuses on conventional Solid state NMR, quantum sensing via color centers and high pressure techniques. After graduation, he is going to be a postdoc researcher on high pressure ODMR in Harvard.

报告摘要

Pressure alters the physical, chemical and electronic properties of matter. The development of the diamond anvil cell (DAC) enables tabletop experiments to investigate a diverse landscape of high-pressure phenomena ranging from the properties of planetary interiors to transitions between quantum mechanical phases. Recently, defects in diamond -- nitrogen-vacancy (NV) color centers have attracted broad attention as quantum sensors. Optically based nuclear magnetic resonance may be possible at pressures greater than a few gigapascals and offers an attractive alternative to conventional Faraday-induction-based detection.Here, we demonstrated the potential to sense the AC field from nuclear spins up to 6 GPa. These experiments enable the possibility of all-optical high resolution magnetic resonance of nanoliter sample volumes at high pressures.
