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…
Dynamical decoupling in interacting systems: applications to signal-enhanced hyperpolarized readout
A. Ajoy, R. Nirodi, A. Sarkar +13
Methods that preserve coherence broadly impact all quantum information processing and metrology applications. Dynamical decoupling methods accomplish this by protecting qubits in n…
Magnetic-field-induced delocalization in hybrid electron-nuclear spin ensembles
Daniela Pagliero, Pablo R. Zangara, Jacob Henshaw +6
We use field-cycling-assisted dynamic nuclear polarization and continuous radio-frequency (RF) driving over a broad spectral range to demonstrate magnetic-field-dependent activatio…
Optically pumped spin polarization as a probe of many-body thermalization
Daniela Pagliero, Pablo R. Zangara, Jacob Henshaw +5
The interplay between disorder and transport is a problem central to the understanding of a broad range of physical processes, most notably the ability of a system to reach thermal…
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…
