Integration of machine learning with neutron scattering for the Hamiltonian tuning of spin ice under pressure

open access: yesCommunications Materials, 2022
Designing and understanding quantum materials requires continuous feedback between experimental observations and theoretical modelling. Here, a machine learning scheme integrates experiments with theory and modelling on experimental timescales for ...

A theoretical study of elastic X-ray scattering [PDF]

open access: yes, 1980
Bragg X-ray scattering intensities are defined as scattering by the thermodynamic average electron-charge density. Purely elastic, kinematic X-ray scattering by a target in thermal equilibrium is always larger than Bragg scattering.

Wideband Radar Echo Frequency-domain Simulation and Analysis for High Speed Moving Targets

open access: yesLeida xuebao, 2014
A frequency-domain method is proposed for wideband radar echo simulation of high-speed moving targets. Based on the physical process of electromagnetic waves observing a moving target, a frequency-domain echo model of wideband radar is constructed, and ...
