Our excited-state mechanical cooling paper is out on arXiv
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.
In this work we experimentally demonstrate a previously unstudied spin-strain interaction in the nitrogen-vacancy (NV) center excited state at room temperature, and theoretically show that it enables cooling of a diamond mechanical resonator using an embedded NV center ensemble.
Our single h-BN defects paper is now posted to 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.
In this paper we characterize the emission wavelengths of sharp, zero-phonon emission of quantum emission from single defects in h-BN. We also study the temperature dependance of the zero phonon lines from two defects, and model the linewidth broadening as interactions with low-frequency phonon in the h-BN sheet of the defect.

Our ZnO polarization spectroscopy paper is posted to 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.

Congratulations Feng!
Our NV mechanical decoupling paper is now posted to the arXiv
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.
In this work we use a single crystal diamond mechanical resonator to protect the spin-state coherence of a single nitrogen-vacancy center spin from magnetic fluctuations.
