Principles and techniques of the quantum diamond microscope [PDF]
Nanophotonics, 2019 We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the quantum diamond microscope (QDM). The QDM employs a dense layer of fluorescent nitrogen-vacancy (NV) color centers near the surface of a ...

Crystals, 2017 Herein, we describe the development of a novel dual air-bearing fixed-χ diffractometer for beamline I19 at Diamond Light Source. The diffractometer is designed to facilitate the rapid data collections possible with a Dectris Pilatus 2M pixel-array photon-

Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet
Nature Communications, 2022 Multipolar magnetic excitations are challenging to measure as most experimental probes are sensitive to dipolar processes. Here, Nag et al. show the existence of dispersing quadrupolar components to the spin excitations in an antiferromagnet ...

Nucleation mechanism for the direct graphite-to-diamond phase transition [PDF]
, 2011 Graphite and diamond have comparable free energies, yet forming diamond from graphite is far from easy. In the absence of a catalyst, pressures that are significantly higher than the equilibrium coexistence pressures are required to induce the graphite ...

JOINT DIAMONDS AND LAVER DIAMONDS [PDF]
The Journal of Symbolic Logic, 2019 Abstract The concept of jointness for guessing principles, specifically ${\diamondsuit _\kappa }$ and various Laver diamonds, is introduced. A family of guessing sequences is joint if the elements of any given sequence of targets may be simultaneously guessed by the members of the family. While equivalent in the case of

Quantum nanophotonics with group IV defects in diamond
Nature Communications, 2019 Diamond photonics is an ever-growing field of research driven by the prospects of harnessing diamond and its colour centres as suitable hardware for solid-state quantum applications. The last two decades have seen the field shaped by the nitrogen-vacancy

Mathematical Proceedings of the Cambridge Philosophical Society, 2010 AbstractInternal diffusion-limited aggregation is a growth model based on random walk in ℤd. We study how the shape of the aggregate depends on the law of the underlying walk, focusing on a family of walks in ℤ2 for which the limiting shape is a diamond.

First principles calculation of lithium-phosphorus co-doped diamond [PDF]
, 2013 We calculate the density of states (DOS) and the Mulliken population of the diamond and the co-doped diamonds with different concentrations of lithium (Li) and phosphorus (P) by the method of the density functional theory, and analyze the bonding ...
