Spectroscopy of composite solid-state spin environments in diamond

ORAL

Abstract

We apply dynamical decoupling pulse sequences to nitrogen-vacancy centers in diamond in order to spectrally decompose the dynamics of their spin environment, which consists of nuclear and electronic spin impurities. We study a variety of diamond samples to identify the dynamics of the different spin baths and the interplay between them. These results are useful for the basic understanding of spin dynamics in solid-state systems and the central spin problem and could inform efforts in engineering optimized samples for collective quantum information processing and quantum metrology.
