Determining the relaxation time from a temperature-dependent scan of the neutron spin-echo signal amplitude [PDF]

open access: yesEPJ Web of Conferences, 2022
Temperature-dependent scans of the neutron scattering intensity are commonly employed in high energy-resolution quasielastic measurements. Besides serving as a useful diagnostic tool for identifying the temperature range that could give rise to a ...

Local pressure calibration method of inductively coupled plasma generator based on laser Thomson scattering measurement

open access: yesScientific Reports, 2022
Based on laser Thomson scattering (TS) measurements and finite element method (FEM) simulations of electron density in inductively coupled plasma (ICP), the simulated local pressure calibration curves of ICP generator are obtained by comparing the ...

Mapping periplasmic binding protein oligosaccharide recognition with neutron crystallography

open access: yesScientific Reports, 2022
Numerous studies have shown how periplasmic binding proteins (PBPs) bind substrates with exquisite specificity, even distinguishing between sugar epimers and anomers, or structurally similar ions.

Unitary Scattering Protected by Pseudo-Hermiticity [PDF]

open access: yesChin. Phys. Lett. 39, 037302 (2022), 2022
The Hermitian systems possess unitary scattering; however, the Hermiticity is unnecessary for a unitary scattering although the scattering under the influence of non-Hermiticity is mostly non-unitary. Here we prove that the unitary scattering is protected by certain type of pseudo-Hermiticity and unaffected by the degree of non-Hermiticity.

Scattering of Skyrmions [PDF]

open access: yesNuclear Physics B, 2015
In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two $B=1$ Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles. We give a qualitative estimate when this approximation breaks down.

A database of synthetic inelastic neutron scattering spectra from molecules and crystals

open access: yesScientific Data, 2023
Inelastic neutron scattering (INS) is a powerful tool to study the vibrational dynamics in a material. The analysis and interpretation of the INS spectra, however, are often nontrivial.

Long-Range Spoof Surface Plasmons(LRSSP) on the Asymmetric Double Metal Gratings

open access: yesIEEE Photonics Journal, 2021
Spoof surface plasmons (SSP) on the corrugated metal surfaces have been widely studied over the past decade in both microwave and Terahertz (THz) band. Previous studies show that SSP mode on the metal grating suffers from high dissipative losses in high ...

The scattering variety [PDF]

open access: yesJournal of High Energy Physics, 2014
The so-called Scattering Equations which govern the kinematics of the scattering of massless particles in arbitrary dimensions have recently been cast into a system of homogeneous polynomials. We study these as affine and projective geometries which we call Scattering Varieties by analyzing such properties as Hilbert series, Euler characteristic and ...
