Universe, 2021 High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description of neutrino–nucleus cross-sections in a broad energy region, going from quasielastic scattering up to ...

Extending MIEZE spectroscopy towards thermal wavelengths
Journal of Applied Crystallography, Volume 55, Issue 6, Page 1424-1431, December 2022., 2022 A modulation of intensity with zero effort (MIEZE) setup is proposed for high‐resolution neutron spectroscopy at momentum transfers up to 3 Å−1, energy transfers up to 20 meV and an energy resolution in the microelectronvolt range using both thermal and cold neutrons.A modulation of intensity with zero effort (MIEZE) setup is proposed for high ...

Impact of composition on the crystal texture and on the dynamics of P(THF-co-ECH) copolymers [PDF]
EPJ Web of Conferences, 2022 We present a combined study by quasielastic neutron scattering (QENS), differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) on poly(tetrahydrofuran-co-epichlorohydrin) copolymers, to see how their composition can be used to tune

Meson-exchange currents and superscaling analysis with relativistic effective mass of quasielastic electron scattering from $^{12}$C [PDF]
Phys. Rev. C 104, 025501 (2021), 2021 We reanalyze the scaling properties of inclusive quasielastic electron scattering from $^{12}$C by subtracting from the data the effects of two-particle emission. A model of relativistic meson-exchange currents (MEC) is employed within the mean field theory of nuclear matter, with scalar and vector potentials that induce an effective mass and a vector ...

Revisiting the modeling of quasielastic neutron scattering from bulk water [PDF]
EPJ Web of Conferences, 2022 Quasi-elastic neutron scattering (QENS) from bulk-water at 300 K, measured on the IRIS backscattering neutron spectrometer (ISIS, UK), is interpreted using the jump diffusion model (JDM), a “minimalistic” multi-timescale relaxation model (MRM) and ...

Dynamics–Function Correlation in Photosystem II: Molecular Dynamics in Solution
Crystals, 2023 A detailed comprehension of protein function requires information on the spatial structure of the protein, which is often gathered from X-ray crystallography.

Soft Phonon Mode Triggering Fast Ag Diffusion in Superionic Argyrodite Ag8GeSe6
Small, Volume 19, Issue 49, December 6, 2023., 2023 Innelastic neutron scattering and Ab‐initio molecular dynamics simulations are employed to unravel that phonon softening on heating to Tc ≈ 350 K triggers fast Ag diffusion in the canonical superionic Argyrodite Ag8GeSe6, which illustrates the microscopic interconnection between soft phonons and mobile ions in superionic materials.

Beyond Rattling: Tetrahedrites as Incipient Ionic Conductors
Advanced Materials, Volume 35, Issue 44, November 2, 2023., 2023 In tetrahedrite, copper ions are mobile at temperatures of 200 K or above, but confined to cages within the crystal structure. The localized diffusional jumps of the copper ions within a confined octahedral environment are effective at suppressing thermal conduction. This work reveals that tetrahedrite behaves as an incipient ionic conductor.

Effect of Intracrystalline Silanol Defects on the Diffusivity of Benzene in Silicalite Zeolite
Chemie Ingenieur Technik, Volume 95, Issue 11, Page 1768-1776, November 2023., 2023 Abstract Intracrystalline zeolite silanol defect groups (≡SiOH) were modelled in silicalite (silica ZSM‐5, MFI) using experimental data. We make a molecular dynamics study on the self‐diffusivity of benzene in silicalite with defects. The simulations at three different loadings (1, 3 and 5 benzene per unit cell) and temperatures (298, 348 and 398 K ...
