Coincidence inelastic neutron scattering for detection of two-spin magnetic correlations [PDF]

open access: yesPhys. Rev. B 103, 054431 (2021), 2020
Inelastic neutron scattering (INS) is one powerful technique to study the low-energy single-spin dynamics of magnetic materials. A variety of quantum magnets show novel magnetic correlations such as quantum spin liquids. These novel magnetic correlations are beyond the direct detection of INS.

NEUTRON SCATTERING AND PHYSISORPTION [PDF]

open access: yesLe Journal de Physique Colloques, 1977
Neutron scattering experiments on methane and ammonia adsorbed on a graphitized carbon black are described. Diffraction from adsorbed deuterated methane shows that, at a coverage of 0.7, it forms an epitaxial layer with a √3 x √3 structure. Between 50 and 60 K it undergoes a phase transition from two-dimensional solid to liquid (bulk melting point = 89.

Three-body coupled channel framework for two-neutron halo nuclei [PDF]

open access: yesarXiv, 2023
We study the Borromean nuclei formed by a core nucleus and two neutrons in a nonrelativistic effective field theory formalism considering both neutron-neutron and neutron-core interactions. We provide formulae of the charge and matter radii, and successfully reproduce the universal relation proposed by Hongo and Son based on the approximation of an ...

Gapless Dirac magnons in CrCl3

open access: yesnpj Quantum Materials, 2022
Bosonic Dirac materials are testbeds for dissipationless spin-based electronics. In the quasi two-dimensional honeycomb lattice of CrX3 (X = Cl, Br, I), Dirac magnons have been predicted at the crossing of acoustical and optical spin waves, analogous to ...

The Schwinger Scattering of Twisted Neutrons by Nuclei [PDF]

open access: yesPhys. Rev. C 100, 051601 (2019), 2019
Thanks to J.~Schwinger, the process of elastic scattering of neutrons by nuclei is known to depend on the interference between a nuclear amplitude and an electromagnetic one for small scattering angles, resulting in spin asymmetries of a cross section or in polarization of the scattered neutrons.

Structural plasticity of SARS-CoV-2 3CL Mpro active site cavity revealed by room temperature X-ray crystallography

open access: yesNature Communications, 2020
The SARS-CoV-2 3CL main protease (3CL Mpro) is a chymotrypsin-like protease that facilitates the production of non-structural proteins, which are essential for viral replication and is therefore of great interest as a drug target.

Investigation of the Impact of Lipid Acyl Chain Saturation on Fusion Peptide Interactions with Lipid Bilayers

open access: yesBiophysica, 2023
The interaction of many peptides with lipid bilayer membranes strongly depends on the lipid composition. Here, a study of the impact of unsaturated lipid acyl chains on the interaction of a derivative of the HIV-1 fusion peptide with lipid bilayer ...

Neutron scattering on nuclei

open access: yesNucleic Acids Research, 1979
Very small angle neutron scattering studies have been made on intact nuclei under a variety of solution conditions. Scattering maxima are observed at 30 to 40 nm and at 18 nm in most environments. Although the spacing, intensity and presence of the maximum near 40 nm varies considerably with environment the 18 nm is rather constant.

Neutron scattering by Dirac multipoles [PDF]

open access: yesJournal of Physics: Condensed Matter, 2017
Ordered magnetic charge created by Dirac multipoles that are magnetic and polar is examined. It has previously been revealed in the pseudo-gap phase of high-Tc materials by use of the Kerr effect and magnetic neutron Bragg diffraction. There are several forms of the polar operator for magnetic neutron scattering built from spin and electric dipole ...
