Effects of entanglement on elastic and inelastic scattering functions for neutron scattering from a pair of nuclei in solids
Hidehiko Sugimoto, Aiko Okumura, 寛之 結城
We calculate the scattering function of neutrons, $S(\stackrel{P\vec}{q},\ensuremath{\omega})$, from a pair of nuclei in entangled states caused by the quantum-mechanical indistinguishability of particles. From the calculation, the conditions for detecting the entanglement of protons in solids by neutron scattering experiments are clarified. Our conclusion is that the entangled state of a proton pair, if it exists, can be observed by performing neutron scattering experiments at very low temperatures for elastic scattering and with high energy resolution for inelastic scattering.
