Excitations of amorphous solid helium
We present neutron scattering measurements of the dynamic structure factor, S(Q, ω), of amorphous solid helium confined in 47 Å pore diameter MCM-41 at pressure 48.6 bar. At low temperature, T = 0.05 K, we observe S(Q, ω) of the confined quantum amorphous solid plus the bulk polycrystalline solid between the MCM-41 powder grains. No liquid-like phonon-roton modes, other sharply defined modes at...
متن کاملExcitations of superfluid helium in porous media
The elementary excitations of superfluid He, characterised by the phonon-roton dispersion curve, have been studied in great detail over the last forty years since the first observation of the roton in a pioneering neutron-scattering experiment in Stockholm in 1957 [1]. The interest today is turning towards the effect of disorder and confinement on these excitations, when e.g. helium is immersed...
متن کاملSelf-Consistent Model of Roton Cluster Excitations in Liquid Helium II
Abstract We have proposed a model of roton cluster excitations in liquid helium II based on a Schrödingertype equation with a self-consistent confining potential. We have derived an equation for the number of atoms in roton excitations, which can be treated as quantum 3D solitons, depending on vibrational quantum numbers. It is shown that the smallest roton cluster is in the symmetric vibration...
متن کاملVortex Photography in Liquid Helium
The study of quantized vortex lines has been advanced hy the technique of vortex photography. This paper prov~dex an overview of the information which has been acquired thus far from this method. Stationary cortex states are ohser\ed which are very similar to those predicted from theory. In addition types of dynamical phenomena are observed. such a\ collective oscillations and the acceleration ...
متن کاملQuantum cavitation in liquid helium.
Using a functional-integral approach, we have determined the temperature below which cavitation in liquid helium is driven by thermally assisted quantum tunneling. For both helium isotopes, we have obtained the crossover temperature in the whole range of allowed negative pressures. Our results are compatible with recent experimental results on He. 64.60.Qb, 64.60.My, 67.80.Gb Typeset using REVT...
