Optical non-reciprocity in magnetic structures related to high-Tc superconductors

, 2011
Recent neutron scattering [1,2], and optical measurements [3,4] have detected evidence in underdoped cuprate superconductors for a phase transition near the pseudogap onset temperature T* to a time reversal-breaking state.

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

Neutron Scattering and Its Application to Strongly Correlated Systems

, 2013
Neutron scattering is a powerful probe of strongly correlated systems. It can directly detect common phenomena such as magnetic order, and can be used to determine the coupling between magnetic moments through measurements of the spin-wave dispersions ...

On the Universal Scattering Time of Neutrons [PDF]

Zeitschrift für Naturforschung A, 2018
Abstract Tunnelling and barrier interaction times of neutrons were previously measured. Here we show that the neutron interaction time with barriers corresponds to the universal tunnelling time of wave mechanics which was formerly observed with elastic, electromagnetic and electron waves.

Neutron$-^{19}$C scattering near an Efimov state

, 2008
The low-energy neutron$-^{19}$C scattering in a neutron-neutron-core model is studied with large scattering lengths near the conditions for the appearance of an Efimov state.

Inelastic neutron scattering [PDF]

EPJ Web of Conferences, 2017
The goal of the JDN22 school was to propose a progressive teaching eager to improve the expertise of students in neutron diffraction. Neutron-based techniques have indeed proved for decades to be essential tools in the investigation of condensed matter. This lecture is however concerned with inelastic neutron scattering and is thus somehow apart.

Determination of silica aerogels nanostructure characteristics by using small angle neutron scattering technique [PDF]

, 2006
Small angle neutron scattering (SANS) technique has been widely employed in probing the microstructure of amorphous materials in the nanometer range (1 to 100 nm).

Quasi-elastic neutron scattering in the high-field phase of a Haldane antiferromagnet

, 2001
Inelastic neutron scattering experiments on the Haldane-gap quantum antiferromagnet NDMAP are performed in magnetic fields below and above the critical field Hc at which the gap closes.

Neutrino Bremsstrahlung in Neutron Matter from Effective Nuclear Interactions

, 2003
We revisit the emissivity from neutrino pair bremsstrahlung in neutron-neutron scattering, nn -> nn nu nubar, which was calculated from the one-pion exchange potential including correlation effects by Friman and Maxwell.
