Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6
Advanced Functional Materials, EarlyView.This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

iScience, 2022 Summary: Terahertz emission from ferromagnetic/non-magnetic spintronic heterostructures had been demonstrated as pump wavelength-independent. We report, however, the pump wavelength dependence of terahertz emission from an optimized Fe/Pt spintronic ...

Four-photon scattering in birefringent fibers [PDF]
, 2008 Four-photon scattering in nonlinear waveguides is an important physical process that allows photon-pair generation in well defined guided modes, with high rate and reasonably low noise. Most of the experiments to date used the scalar four-photon scattering process in which the pump photons and the scattered photons have the same polarization.

Photon discerner: Adaptive quantum optical sensing near the shot noise limit [PDF]
arXiv, 2023 Photon statistics of an optical field can be used for quantum optical sensing in low light level scenarios free of bulky optical components. However, photon-number-resolving detection to unravel the photon statistics is challenging. Here, we propose a novel detection approach, that we call `photon discerning', which uses adaptive photon thresholding ...

Aspherical photon and anti-photon surfaces
Physics Letters B, 2016 In this note we identify photon surfaces and anti-photon surfaces in some physically interesting spacetimes, which are not spherically symmetric. All of our examples solve physically reasonable field equations, including for some cases the vacuum Einstein equations, albeit they are not asymptotically flat.

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide
Advanced Functional Materials, EarlyView.An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

HIGH ENERGY PHOTON-PHOTON AND ELECTRON-PHOTON COLLISIONS [PDF]
International Journal of Modern Physics A, 1998 The advent of a next linear e±e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ*γ*→X in the region dominated by BFKL hard Pomeron exchange and report the ...
