Utilizing nitrogen-vacancy centers to measure oscillating magnetic fields [PDF]
Physical Review A, 2014 We show how nitrogen vacancy (NV) centers can be used to determine the amplitude, phase and frequency of unknown weak monochromatic and multichromatic oscillating magnetic fields using only the periodic dynamical decoupling (PDD) and Carr-Purcell-Meiboom-Gill (CPMG) sequences.

Coupling Nitrogen-Vacancy Centers in Diamond to Superconducting Flux Qubits [PDF]
Physical Review Letters, 2010 We propose a method to achieve coherent coupling between Nitrogen-vacancy (NV) centers in diamond and superconducting (SC) flux qubits. The resulting coupling can be used to create a coherent interaction between the spin states of distant NV centers mediated by the flux qubit.

Advanced Engineering Materials, EarlyView.This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Vibrational and electronic ultrafast relaxation of the nitrogen-vacancy centers in diamond
EPJ Web of Conferences, 2013 Two dimensional electronic spectroscopy and transient grating measurements were performed, for the first time, on nitrogen-vacancy centers in diamond. These measurements reveal energy transfer and vibrational pathways with consequences for spin coherence.

Perfectly Aligned Shallow Ensemble Nitrogen-Vacancy Centers in (111) Diamond
, 2017 We report the formation of perfectly aligned, high-density, shallow nitrogen vacancy (NV) centers on the ($111$) surface of a diamond. The study involved step-flow growth with a high flux of nitrogen during chemical vapor deposition (CVD) growth, which ...

Single Nitrogen Vacancy Centers in Chemical Vapor Deposited Diamond Nanocrystals [PDF]
Nano Letters, 2007 Nanodiamond crystals containing single color centers have been grown by chemical vapor deposition (CVD). The fluorescence from individual crystallites was directly correlated with crystallite size using a combined atomic force and scanning confocal fluorescence microscope.

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Spatio-temporal second-order quantum correlations of surface plasmon polaritons
, 2015 We present an experimental methodology to observe spatio-temporal second-order quantum coherence of surface plasmon polaritons which are emitted by nitrogen vacancy color centers attached at the apex of an optical tip.

Low-Field Nuclear Polarization Using Nitrogen Vacancy Centers in Diamonds [PDF]
Physical Review Letters, 2018 It was recently demonstrated that bulk nuclear polarization can be obtained using Nitrogen Vacancy (NV) color centers in diamonds, even at ambient conditions. This is based on the optical polarization of the NV electron spin, and using several polarization transfer methods.
