Periodicity and stability in neutral nonlinear dynamic equations with functional delay on a time scale

open access: yesElectronic Journal of Differential Equations, 2007
Let $mathbb{T}$ be a periodic time scale. We use a fixed point theorem due to Krasnosel'skii to show that the nonlinear neutral dynamic equation with delay $$ x^{Delta}(t) = -a(t)x^{sigma}(t) + left(Q(t,x(t), x(t-g(t)))) ight)^{Delta} + Gig(t,x(t), x(t-g(

Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.

Periodic solutions for a second-order neutral differential equation with variable parameter and multiple deviating arguments

open access: yesElectronic Journal of Differential Equations, 2010
By employing the continuation theorem of coincidence degree theory developed by Mawhin, we obtain periodic solution for a class of neutral differential equation with variable parameter and multiple deviating arguments.

Is Everything Neutral? [PDF]

open access: yes
In his well-known analysis of the national debt, Robert Barro introduced the notion of a "dynastic family." This notion has since become a standard research tool, particularly in the areas of public finance and macroeconomics.

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...
