In this paper, a deep-inelastic (Compton) neutron scattering experiment on mixtures at $T\phantom{\rule{0ex}{0ex}}= \phantom{ 0ex}0ex}293\mathrm{K}$ has been carried out.Abstract:
A deep-inelastic (Compton) neutron scattering experiment on ${\mathrm{H}}_{2}\mathrm{O}\ensuremath{-}{\mathrm{D}}_{2}\mathrm{O}$ mixtures at $T\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}293\mathrm{K}$ has been carried out. Well-resolved H and D neutron recoil peaks in the time-of-flight spectra permit the direct determination of the ratio $Q\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}{\ensuremath{\sigma}}_{\mathrm{H}}/{\ensuremath{\sigma}}_{\mathrm{D}}$ of the H and D total cross sections. In contrast to every conventional expectation, $Q$ has been observed to vary strongly with the H-D composition. This striking effect provides, for the first time, direct evidence for short-lived entanglement of adjacent protons (deuterons) in condensed matter at room temperature.read more

Decoherence, einselection, and the quantum origins of the classical
TL;DR: In this article, it was shown that many of the symptoms of classicality can be induced in quantum systems by their environments, which leads to environment-induced superselection or einselection, a quantum process associated with selective loss of information.

Measurement of momentum distribution of lightatoms and molecules in condensed matter systems using inelastic neutron scattering
TL;DR: In this article, a review of single-particle momentum distributions in light atoms and molecules is presented with specific emphasis on experimental measurements using the deep inelastic neutron scattering technique at eV energies.

Anomalous neutron Compton scattering in Nb hydride: Indications of proton correlations
Erik B. Karlsson,C. A. Chatzidimitriou-Dreismann,T. Abdul-Redah,R. M. F. Streffer,Björgvin Hjörvarsson,J. Öhrmalm,J Mayers +6 more
TL;DR: Very strong anomalies in the cross-sections for protons were observed for scattering on NbHx and Nb HxDy as mentioned in this paper, which indicates some kind of very short-lived correlations.

Quantum entanglement and neutron scattering experiments
TL;DR: In this paper, it is shown that quantum entanglement in condensed matter can be observed with scattering experiments if the energy resolution of the experiments enables a clear separation between the elastic scattering and the scattering from the excitations in the system.

The measurement of anomalous neutron inelastic cross-sections at electronvolt energy transfers
J Mayers,T Abdul-Redah +1 more
TL;DR: In this paper, it was shown that the assumption of a Gaussian peak shape for the neutron Compton profile can introduce significant errors into the determination of cross-section ratios, but also cannot explain the observed anomalies.

Path integral approach to quantum Brownian motion
TL;DR: In this paper, the authors apply the influence-functional method of Feynman and Vernon to the study of Brownian motion at arbitrary temperature and obtain an explicit expression for the time evolution of the complete density matrix ϱ(x, x, x′, t) when the system starts in a particular kind of pure state.

Decoherence and the transition from quantum to classical
TL;DR: In this paper, the authors argue that without quantum physics we could not explain the behavior of solids, the structure and function of DNA, the color of the stars, the action of lasers or the properties of superfluids.

On the quantum nature of the shared proton in hydrogen bonds
TL;DR: The relative influence of thermal and quantum fluctuations on the proton transfer properties of the charged water complexes H5O2+ and H3O2− was investigated with the use of ab initio techniques and found that quantum zero-point motion played a crucial role even at room temperature.

Phase uncertainty and loss of interference: A general picture
TL;DR: The equivalence of the two approaches to quantum interference in the presence of an environment is proven and dephasing of electron interference by photon modes in coherent and thermal states and by electromagnetic fluctuations in metals is proven.

Multiparticle Interferometry and the Superposition Principle
TL;DR: Superposition may be the only true quantum mystery, but in multiparticle systems the principle yields phenomena that are much richer and more interesting than anything that can be seen in one-particle systems as discussed by the authors.
