The Laboratory for Nano-Optics deeply regrets the tragic accident and the death of Dr. Dmitry Fedyanin. We express our sincere condolences to Dmitry's family and friends. Dmitry was a recipient of a Walter Benjamin Position of the DFG on “Pulsed electrically driven single-photon sources on diamond” and since July 2023 he has been a research associate in our group. We have been collaborating since almost a decade on the electroluminescence from color centers in diamond. We mourn the loss of a good friend and of a talented young scientist.
