Room temperature "Optical Nanodiamond Hyperpolarizer": physics, design and operation
Ashok Ajoy, Raffi Nazaryan, Emanuel Druga +12
Dynamic Nuclear Polarization (DNP) is a powerful suite of techniques that deliver multifold signal enhancements in NMR and MRI. The generated athermal spin states can also be explo…
Toward the Identification of Atomic Defects in Hexagonal Boron Nitride: X-Ray Photoelectron Spectroscopy and First-Principles Calculations
Gabriel I. López-Morales, Nicholas V. Proscia, Gustavo E. López +2
Defects in hexagonal boron nitride (hBN) exhibit single-photon emission (SPE) and are thus attracting broad interest as platforms for quantum information and spintronic application…
Spin readout via spin-to-charge conversion in bulk diamond nitrogen-vacancy ensembles
Harishankar Jayakumar, Siddharth Dhomkar, Jacob Henshaw +1
We demonstrate optical readout of ensembles of nitrogen-vacancy(NV) center spins in a bulk diamond sample via spin-to-charge conversion. A high power 594 nm laser is utilized to se…
Wide dynamic range magnetic field cycler: Harnessing quantum control at low and high fields
A. Ajoy, X. Lv, E. Druga +11
We describe the construction of a fast field cycling device capable of sweeping a 4-order-of-magnitude range of magnetic fields, from ~1mT to 7T, in under 700ms. Central to this sy…
Enhanced dynamic nuclear polarization via swept microwave frequency combs
A. Ajoy, R. Nazaryan, K. Liu +9
Dynamic Nuclear Polarization (DNP) has enabled enormous gains in magnetic resonance signals and led to vastly accelerated NMR/MRI imaging and spectroscopy. Unlike conventional cw-t…
Charge dynamics in near-surface, variable-density ensembles of nitrogen-vacancy centers in diamond
Siddharth Dhomkar, Harishankar Jayakumar, Pablo R. Zangara +1
Although the spin properties of superficial shallow nitrogen-vacancy (NV) centers have been the subject of extensive scrutiny, considerably less attention has been devoted to study…
