Excitations 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 کاملMutual Friction and the Thermal Conductivity of Superfluid Helium Near
Temperature gradients in superfluid helium carrying a heat current in a 13.8-ram-wide tube or in a O.l-mm-wide slit have been measured at 0.09 m°K < T z T < 16 m°K. The results are interpreted in terms of a mutual friction force between the normal component of He II and vortices in its counterflowing superfluid component. This force is found to diverge near Tz with a mutual friction constant pr...
متن کاملUCNproduction bymultiphonon processes in superfluid Helium under pressure
Cold neutrons are converted to ultra-cold neutrons (UCN) by the excitation of a single phonon or multiphonons in superfluid helium. The dynamic scattering function S(q, ω) of the superfluid helium strongly depends on pressure, leading to a pressuredependent differential UCN production rate. A phenomenological expression for the multiphonon part of the scattering function s(λ) describing UCN pro...
متن کاملStatic response function for longitudinal and transverse excitations in superfluid helium.
The sum rule formalism is used to evaluate rigorous bounds for the density and current static response functions in superfluid He at zero temperature. Both lower and upper bounds are considered. The bounds are expressed in terms of ground state properties (density and current correlation functions) and of the interatomic potential. The results for the density static response significantly impro...
متن کاملNanoparticle dispersion in superfluid helium.
Cryogenic fluid flows including liquid nitrogen and superfluid helium are a rich environment for novel scientific discovery. Flows can be measured optically and dynamically when faithful tracer particles are dispersed in the liquid. We present a reliable technique for dispersing commercially available fluorescent nanoparticles into cryogenic fluids using ultrasound. Five types of fluorescent na...
