Crystal-like high frequency phonons in the amorphous phases of solid water
H. Schober, M. M. Koza, A. Toelle +3
The high frequency dynamics of low- (LDA) and high-density amorphous-ice (HDA) and of cubic ice (I_c) has been measured by inelastic X-ray Scattering (IXS) in the 1-15 nm^{-1} mome…

Dynamics of liquid 4He in Vycor
H. R. Glyde, O. Plantevin, B. Fak +3
We have measured the dynamic structure factor of liquid 4He in Vycor using neutron inelastic scattering. Well-defined phonon-roton (p-r) excitations are observed in the superfluid…
