Neutron scattering studies of K $_{3}$ H(SO $_{4})_{2}$ and K $_{3}$ D(SO $_{4})_{2}$ : The particle-in-a-box model for the quantum phase transition

François Fillaux, Alain Cousson

In the crystal of K $_{3}$ H(SO $_{4})_{2}$ , or K $_{3}$ D(SO $_{4})_{2}$ , dimers (SO $_{4}) ...$ H $...$ (SO $_{4})$ , or (SO $_{4}) ...$ D $...$ (SO $_{4})$ , are linked by strong centrosymmetric hydrogen or deuterium…

Evidence of macroscopically entangled protons in a mixed isotope crystal of KH $_{p}$ D $_{1 - p}$ CO $_{3}$

François Fillaux, Alain Cousson, Matthias J. Gutmann

We examine whether protons and deuterons in the crystal of KH $_{0.76}$ D $_{0.24}$ CO $_{3}$ at 300 K are particles or matter waves. The neutron scattering function measured over a broad…

The macroscopic quantum behavior of protons in the KHCO_3 crystal: Theory and experiments

François Fillaux, Alain Cousson, Matthias J. Gutmann

For hydrogen bonded crystals exhibiting proton transfer along hydrogen bonds, namely $O1 - H ... O2 ⟷ O1 ... H - O2$ , there is a dic…

Where are Protons and Deuterons in KH_pD_{1-p}CO_3? A Neutron Diffraction Study

François Fillaux, Alain Cousson

The crystals of potassium hydrogen carbonate (KHCO3) and the KDCO3 analogue are isomorphous. They are composed of hydrogen or deuterium bonded centrosymmetric dimers (HCO3-)(2) or…

Nonlocal protons and deuterons opposed to disorder: a single-crystal neutron diffraction study of KH0.76D0.24CO3 and a theoretical framewok

François Fillaux, Alain Cousson

We show with neutron diffraction that a single-crystal of potassium hydrogen deuterium carbonate at room temperature, namely KH $_{0.76}$ D $_{0.24}$ CO $_{3}$ , is isomorphous with the KH…

A neutron diffraction study of macroscopically entangled proton states in the high temperature phase of the KHCO3 crystal at 340 K

François Fillaux, Alain Cousson, Matthias J. Gutmann

We utilize single-crystal neutron diffraction to study the $C 2/ m$ structure of potassium hydrogen carbonate (KHCO $_{3}$ ) and macroscopic quantum entanglement above the phase transiti…
