Measuring strain in diamond using spectroscopy of silicon vacancy centers

Abstract: Color centers in diamond are defects which have shown promise in quantum information and sensing applications. One such defect, the negatively charged silicon-vacancy (SiV) center, has properties which make it particularly well suited for some of these applications. One way that we can study these systems is using optical spectroscopy, which typically measures the light emitted or absorbed by a system as a function of its frequency or color. In this talk, I will discuss experimental results I have obtained using several spectroscopy techniques. In particular, multidimensional coherent spectroscopy (MDCS), a form of nonlinear spectroscopy, can be used to obtain a large amount of information about a system from a single dataset. I will focus on how we can use MDCS of SiV centers to measure the strain present in our sample. I will also talk a bit about my experience as a graduate student.
Bio: Kelsey Bates received her Ph.D. in physics from the University of Michigan in 2024. There, she worked with Dr. Steven Cundiff on several projects related to multidimensional coherent spectroscopy. In 2017, she received a B.S. in physics and mathematics from the University of Washington, where she worked with Dr. Kai-Mei Fu.
