Towards Hyperpolarization at the Solid Surface - A Progress Report — •Konstantin Herb and Christian Degen — Department of Physics, ETH Zurich, Switzerland

Traditionally, nuclear magnetic resonance (NMR) spectroscopy suffers from intrinsically low sensitivity due to the relatively weak coupling of nuclear spins to an external magnetic field. To significantly enhance the sensitivity of NMR spectroscopy, electron spins may be used as a polarizing source. Transferring nuclear spin polarization from the Nitrogen-Vacancy (NV) center to its surrounding is a long-standing goal in field. In this talk, I will present our recent progress towards achieving hyperpolarization at the solid surface. We explore the possibilities and limits of transferring polarization from NV centers to the surface of diamond. We will discuss the challenges we face in this process, including the need for efficient transfer mechanisms and the optimization of experimental conditions.
