Room-temperature spontaneous superradiance from single diamond nanocrystals. Bradac, C., Johnsson, M., Van Breugel, M., Baragiola, B., Martin, R., Juan, M., Brennen, G., & Volz, T. Nature Communications, 2017.
Link doi abstract bibtex Superradiance (SR) is a cooperative phenomenon which occurs when an ensemble of quantum emitters couples collectively to a mode of the electromagnetic field as a single, massive dipole that radiates photons at an enhanced rate. Previous studies on solid-state systems either reported SR from sizeable crystals with at least one spatial dimension much larger than the wavelength of the light and/or only close to liquid-helium temperatures. Here, we report the observation of room-temperature superradiance from single, highly luminescent diamond nanocrystals with spatial dimensions much smaller than the wavelength of light, and each containing a large number (∼103) of embedded nitrogen-vacancy (NV) centres. The results pave the way towards a systematic study of SR in a well-controlled, solid-state quantum system at room temperature. © 2017 The Author(s).
