The Cornell Chronicle covered our recent award from the Department of Energy to advance Quantum Information Science in collaboration with Dan Ralph (Cornell Physics), Ezekiel Johnston-Halperin (Ohio State U.), and Michael Flattè (U. Iowa). Check it out: https://news.cornell.edu/stories/2021/08/researchers-receive-54m-advance-quantum-science
The Cornell Chronicle coverage of our recent near-field magneto-thermal microscopy paper: Magneto-thermal imaging brings synchrotron capabilities to the lab.
Our Paper “Nanoscale Magnetization and Current Imaging Using Time-Resolved Scanning-Probe Magnetothermal Microscopy,” by Chi Zhang, Jason Bartell, Jonathan Karsch, Isaiah Gray and Gregory Fuchs is now out at Nano Letters.
We have recently posted two new papers to the arXiv:
- “Raman Spectroscopy and Aging of the Low-Loss Ferrimagnet Vanadium Tetracyanoethylene” by H. F. H. Cheung, M. Chilcote, H. Yusuf, D. S. Cormode, Y. Shi, M. E. Flatté, E. Johnston-Halperin, and G. D. Fuchs. Here we use Raman spectrocopy correlated with ferromagnetic resonance and SQUID magnetometry to understand the processes that lead to chemical breakdown of the low-loss ferrimagnet V[TCNE]2. This material is exciting for coherent magnonics and quantum magnonics (see some ideas discussed here).
- “Nanoscale magnetization and current imaging using scanning-probe magneto-thermal microscopy” by Chi Zhang, Jason M. Bartell, Jonathan C. Karsch, Isaiah Gray, and Gregory D. Fuchs. Here we demonstrate a near-field scanning magneto-thermal microscope. This instrument can image both magnetization and current density with 100 nm scale spatial resolution and sub-100 ps scale temporal resolution. This is exciting because there is a dearth of magnetic microscopies that combine these two capabilities, and the ones that exist are mainly beamline techniques. Our approach is a table-top microscopy and comparably low cost.
Our paper, “Operando Control of Skyrmion Density in a Lorentz Transmission Electron Microscope with Current Pulses,” by A. M. Park, Z. Chen, X. S. Zhang, L. Zhu, D. A. Muller, and G. D. Fuchs has now been published in the Journal of Applied Physics. Congratulations Albert!
The Cornell Chronicle highlighted our paper demonstrating single quantum driving with acoustic waves: Acoustics put a fresh spin on electron transitions.
Our paper “Local Photothermal Control of Phase Transitions for On-Demand Room-Temperture Rewritable Magnetic Patterning” was featured on the inside cover of Advanced Materials and covered in the covered by the Cornell Chronicle.
Our paper, “Acoustically driving the single quantum spin transition of diamond nitrogen-vacancy centers” by H. Y. Chen, S. A. Bhave, and G. D. Fuchs is now out at Phys. Rev. Applied.
Congratulations to Dr. Huiyao Chen for successfully defending his thesis, “Quantum Acoustic Control of Diamond Nitrogen-Vacancy Centers.”
