Quantum wake dynamics in Heisenberg antiferromagnetic chains

Nature Communications, 2022
It has long been suggested that the inverse Fourier transform of neutron scattering data gives access to space- and time-resolved spin-spin correlations. Scheie et al.

Neutron Total Scattering and Inelastic Neutron Scattering

Nihon Kessho Gakkaishi, 2004
Measurement of total scattering, which includes both the Bragg peaks and the diffuse scattering, can give information about the short-range structure of materials. This is quite useful for understanding the structure of liquid, glasses and amorphous materials.

Observability of an induced electric dipole moment of the neutron from nonlinear QED [PDF]

, 2011
It has been shown recently that a neutron placed in an external quasistatic electric field develops an induced electric dipole moment $\mathbf{p}_{\mathrm{IND}}$ due to quantum fluctuations in the QED vacuum. A feasible experiment which could detect such

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]

, 2016
We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential
