Abstract:

In recent years, the negatively charged nitrogen- vacancy (NV) center has emerged as a promising solid-state color center capable of measuring magnetic fields with high sensitivity and spatial resolution under ambient conditions. In my defense, I will discuss how we perform super resolution magnetic microscopy and acquire magnetic field images of nanoparticle samples at 100 nm resolution. I will explain how 3D flux concentrators increase magnetic field amplitude and allows us to measure vector component magnetic fields as low as 300 µT with a diamond magnetometer, without the use of an additional bias magnetic field. I also describe how optical interference patterns could replace the single donut approach in super resolution microscopy when performing wide field imaging. 

Biography:

Nazanin earned her Bachelor of Science in Physics from Kharazmi University and later completed her Master of Science in Medical Physics at Indiana University Bloomington. During her master's program, she designed and developed a sensor based on surface plasmon resonance, focusing on the bonding of glucose molecules to a functionalized gold surface. As a PhD student at the University of New Mexico (UNM), Nazanin has been a member of Dr. Acosta's research group, working on nitrogen vacancy centers in diamond and their applications. She also obtained a Master of Science in Optical Science and Engineering (OSE) from UNM.
