Photoluminescence at the ground state level anticrossing of the nitrogen-vacancy center in diamond
Viktor Ivády, Huijie Zheng, Arne Wickenbrock +9
The nitrogen-vacancy center (NV center) in diamond at magnetic fields corresponding to the ground state level anticrossing (GSLAC) region gives rise to rich photoluminescence (PL)…
Coherent electrical readout of defect spins in 4H-SiC by photo-ionization at ambient conditions
Matthias Niethammer, Matthias Widmann, Torsten Rendler +11
Quantum technology relies on proper hardware, enabling coherent quantum state control as well as efficient quantum state readout. In this regard, wide-bandgap semiconductors are an…
Robust and accurate electric field sensing with solid state spin ensembles
Julia Michl, Jakob Steiner, Andrej Denisenko +8
Electron spins in solids constitute remarkable quantum sensors. Individual defect centers in diamond were used to detect individual nuclear spins with nanometer scale resolution, a…
Solid-state electron spin lifetime limited by phononic vacuum modes
Thomas Astner, Johannes Gugler, Andreas Angerer +10
Longitudinal relaxation is the process by which an excited spin ensemble decays into its thermal equilibrium with the environment. In solid-state spin systems relaxation into the p…
Critical thermalization of a disordered dipolar spin system in diamond
Georg Kucsko, Soonwon Choi, Joonhee Choi +10
Statistical mechanics underlies our understanding of macroscopic quantum systems. It is based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium s…
Perfect alignment and preferential orientation of nitrogen-vacancy centers during CVD growth of diamond on (111) surfaces
Julia Michl, Tokuyuki Teraji, Sebastian Zaiser +8
Synthetic diamond production is key to the development of quantum metrology and quantum information applications of diamond. The major quantum sensor and qubit candidate in diamond…
Sensing remote nuclear spins
Nan Zhao, Jan Honert, Berhard Schmid +7
Sensing single nuclear spins is a central challenge in magnetic resonance based imaging techniques. Although different methods and especially diamond defect based sensing and imagi…
