Our paper "Cooling a Mechanical Resonator with a Nitrogen-Vacancy Center Ensemble Using a Room Temperature Excited State Spin-Strain Interaction" by E. R. MacQuarrie, M. Otten, S. K. Gray, and G. D. Fuchs is now availible on the arXiv.
Our manuscript "Temperature Dependence of Wavelength Selectable Zero-Phonon Emission from Single Defects in Hexagonal Boron Nitride" by Nicholas R. Jungwirth, Brian Calderon, Yanxin Ji, Michael G. Spencer, Michael E. Flatté, and Gregory D. Fuchs is now posted to the arXiv.
Our paper "Polarization spectroscopy of defect-based single photon sources in ZnO" by N. R. Jungwirth, H. -S. Chang, M. Jiang, and G. D. Fuchs has been posted to the arXiv. In this work we show that a yet unidentified single-defect based quantum emitter in ZnO has a Z-type optical dipole, which implies that it has orbital singlet states in both the ground and excited state.

Our paper "Continuous dynamical decoupling of a single diamond nitrogen-vacancy center spin with a mechanical resonator" by E. R. MacQuarrie, T. A. Gosavi, S. A. Bhave, and G. D. Fuchs has been posted to the arXv.
Our paper "Towards a table-top microscope for nanoscale magnetic imaging using picosecond thermal gradients" has now been published in Nature Communications. Also catch coverage in the Cornell Chronicle: Physicists turn toward heat to study electron spin.
Congratulations to Dr. Darryl Ngai, who successfully defended his thesis "Using Picosecond Heat Pulses to Measure Magnetization."
Congratulations to Isaiah Gray for being selected a graduate fellow of the Kavli Institute at Cornell for Nanoscale Science. He will recieve the Watt W. Webb fellowship.
