Phonon lifetimes are a key component of quasiparticle theories transport; yet first-principles rarely directly compared with inelastic neutron scattering (INS) results. Existing comparisons show discrepancies even at temperatures where perturbation theory is expected to be reliable. In this paper, we demonstrate that the reciprocal space voxel ($q$ voxel), which finite region in required INS da...

A new method is presented to calibrate an X-ray energy scale with sub-meV relative accuracy by using the detailed-balance principle of the phonon creation and annihilation. This method is conveniently used to define or verify the energy scale of high-energy-resolution monochromators that are used in inelastic X-ray scattering and nuclear resonant inelastic X-ray scattering instruments at synchr...

Abstract Measuring the pionic structure function is of high interest, as it provides a new area for understanding strong interaction among quarks and testing QCD predictions. To this end, we investigate feasibility expected impact possible experiment at EicC (Electron-ion collider in China). We show simulation results on statistical precision an measurement, based model leading neutron tagged D...
