Bose-Einstein vs. electrodynamic condensates: the question of order and coherence
E. Del Giudice, G. Preparata
The remarkable recent experiments on ensembles of magnetically trapped ultracold alkali atoms have demonstrated the transition to a highly ordered phase, that has been attributed t…
A tale of two condensates: the odd "Bose - Einstein" condensation of atomic Hydrogen
E. Del Giudice, G. Preparata
The recent report of the observation of Bose-Einstein condensation in atomic Hydrogen, characterized by an "anomalous" density spectrum, is shown to be in agreement with the predic…
Anomalies in H2O-D2O mixtures: Evidence for the Two-Fluid Structure of Water
M. Buzzacchi, E. Del Giudice, G. Preparata
Recent probing of H2O-D2O mixtures by various means (neutron deep-inelastic scattering, Raman absorption, electrical H+/D+ conductivity) revealed an unexpected dependence of the re…
Comment on "Anomalous Deep Inelastic Scattering from Liquid H2O-D2O: Evidence of Nuclear Quantum Entanglement"
Matteo Buzzacchi, Emilio Del Giudice, Giuliano Preparata
We comment some recent unexpected experimental results on proton/deuteron deep inelastic scattering off water molecules in H2O-D2O mixtures (C.A. Chatzidimitrou-Dreismann et al. Ph…
On the Dielectric Instability of High-Pressure Hydrogen
M. Buzzacchi, E. Del Giudice, G. Preparata +1
We present a comment on a recent letter by B. Edwards, N.W. Ashcroft, Nature 388 (1997) 652, in which the dielectric instabilty of the phase III of the solid molecular hydrogen sys…
