Special AMO/QO Physics Lunch Seminar

"Magnetic resonance spectroscopy on a diamond chip"

Dr. Victor Acosta
University of New Mexico


I will discuss our lab's latest results in developing a diamond-chip-based platform for determining composition, structure, and function of trace biochemical analytes via nuclear magnetic resonance (NMR), nuclear quadrupole resonance (NQR), and electron paramagnetic resonance (EPR) spectroscopies. The platform consists of non-inductive optical detection of Nitrogen-Vacancy (NV) color centers doped into dense, high-aspect-ratio nanogratings. It features high sensitivity in a wide range of magnetic fields and at ambient temperature. We have recently demonstrated solution-state NMR, NQR detection of thin films, and EPR detection of external spins with this platform.
