Dynamic-nuclear-polarization-weighted spectroscopy of multi-spin electronic-nuclear clusters
Roberta Pigliapochi, Daniela Pagliero, Lisandro Buljubasich +4
Nuclear spins and paramagnetic centers in a solid randomly group to form clusters featuring nearly-degenerate, hybrid states whose dynamics are central to processes involving nucle…
Detection and modeling of hole capture by single point defects under variable electric fields
Artur Lozovoi, YunHeng Chen, Gyorgy Vizkelethy +4
Understanding carrier trapping in solids has proven key to semiconductor technologies but observations thus far have relied on ensembles of point defects, where the impact of neigh…
Semiempirical modeling of bound states of deep defects in semiconductor quantum technologies
YunHeng Chen, Lachlan Oberg, Johannes Flick +3
A significant hurdle in developing high-performance semiconductor quantum technologies utilizing deep defects is related to charge dynamics. Unfortunately, progress in modeling the…
Room-temperature photo-chromism of silicon vacancy centers in CVD diamond
Alexander Wood, Artur Lozovoi, Zi-Huai Zhang +5
The silicon-vacancy (SiV) center in diamond is typically found in three stable charge states, SiV0, SiV- and SiV2-, but studying the processes leading to their formation is challen…
Spin dynamics of a solid-state qubit in proximity to a superconductor
Richard Monge, Tom Delord, Nicholas Proscia +11
A broad effort is underway to understand and harness the interaction between superconductors and spin-active color centers with an eye on the realization of hybrid quantum devices…
Imaging dark charge emitters in diamond via carrier-to-photon conversion
Artur Lozovoi, Gyorgy Vizkelethy, Edward Bielejec +1
The application of color centers in wide-bandgap semiconductors to nanoscale sensing and quantum information processing largely rests on our knowledge of the surrounding crystallin…
Optical activation and detection of charge transport between individual color centers in room-temperature diamond

Charge control of color centers in semiconductors promises opportunities for novel forms of sensing and quantum information processing. Here, we articulate confocal fluorescence mi…
Investigation of photon emitters in Ce-implanted hexagonal boron nitride
Gabriel I. López-Morales, Mingxing Li, Alexander Hampel +9
Color centers in hexagonal boron nitride (hBN) are presently attracting broad interest as a novel platform for nanoscale sensing and quantum information processing. Unfortunately,…
Probing metastable space-charge potentials in a wide bandgap semiconductor
Artur Lozovoi, Harishankar Jayakumar, Damon Daw +2
While the study of space charge potentials has a long history, present models are largely based on the notion of steady state equilibrium, ill-suited to describe wide bandgap semic…
Dark defect charge dynamics in bulk chemical-vapor-deposition-grown diamonds probed via nitrogen vacancy centers
A. Lozovoi, D. Daw, H. Jayakumar +1
Although chemical vapor deposition (CVD) is one of the preferred routes to synthetic diamond crystals, a full knowledge of the point defects produced during growth is still incompl…
Long-term spin state storage using ancilla charge memories
Harishankar Jayakumar, Artur Lozovoi, Damon Daw +1
We articulate confocal microscopy and electron spin resonance to implement spin-to-charge conversion in a small ensemble of nitrogen-vacancy (NV) centers in bulk diamond, and demon…
On the theory of proton solid echo in polymer melts
N. Fatkullin, A. Lozovoi, C. Mattea +1
Based on a modified Anderson-Weiss approximation (N. Fatkullin, A. Gubaidullin, C. Mattea, S.Stapf, J. Chem. Phys. 137 (2012), 224907) an improved theory of proton spin solid echo…
