Greg will particpate and lecture at the B2/ITAMP Winterschool this January, 2015. This year’s topic is “Hybrid Quantum Systems.”
Our new coherent mechanical spin control paper is out on arXiv
Our paper “Coherent Control of a Nitrogen-Vacancy Center Spin Ensemble with a Diamond Mechanical Resonator” has now been posted to the arXiv.
Welcome new postdocs Emrah Turgut and Feng Guo!
Emrah Turgut joins us from the University of Colorado and JILA where he studied ultrafast demagnetization and related physics. Feng Guo joins our group from NIST at Gaithesburg where he used ferromagnetic resonance force microscopy to image dynamics in magnetic nanostructures. Welcome Emrah and Feng!
Feng Guo research seminar
Feng Guo will be presenting his work at NIST this Monday Aug. 4 at 10:30 am in 220 Clark.
Spin waves at work: Imaging and Characterization of Magnetic Nanostructures
Abstract:
Many of the applications for magnetic nanotechnology depend on the ability to characterize the magnetic properties on the nanoscale. At NIST, we have been developing a ferromagnetic resonance force microscopy (FMRFM) facilitywith the goal of developing diagnostic measurements for practical devices. Conceptually, FMRFM may be regarded as a microwave spectrometer with a scanned probe detector, and it has the ability to “see” the ferromagnetic resonance spectra of buried structures. In the first example, I will describe the defect detection in an array by using spin wave resonance as a contrast mechanism. In another set of measurements, we investigate confined spin wave modes in patterned structures, and we demonstrate the ability to characterize the film edge properties. Throughout the talk I will attempt to emphasize the simple physics of the spin waves and its application to technological problems will be discussed in the context of developing scalable quantum information processing on a chip.

Talk and poster at PASPS VIII
We’re excited to present one talk and one poster on our research at the upcoming PASPS VIII meeting in Washington, D.C. The talk will be “Driving diamond nitrogen-vacancy center spins with mechanical motion” presented by Professor Fuchs. The poster will be “Single Photon Emission from Defects in Sputtered ZnO Films” by N. R. Jungwirth, H. S. Chang, Y. Y. Pai, and G. D. Fuchs presented by Hung. Come see them!
