Critical Landau velocity in helium nanodroplets.
The best-known property of superfluid helium is the vanishing viscosity that objects experience while moving through the liquid with speeds below the so-called critical Landau velocity. This critical velocity is generally considered a macroscopic property as it is related to the collective excitations of the helium atoms in the liquid. In the present work we determine to what extent this concep...
متن کاملElastic Properties of Polycrystalline Solid Helium
Recent experiments have shown that the shear modulus of solid helium undergoes a large temperature variation in the range 20 to 200 mK, possibly due to changes in the pinning of dislocations. In this note we report on computer simulations of the elastic properties of polycrystalline solid helium. We calculate how the elastic coefficients of a sample made up of a large number of randomly oriente...
متن کاملHELIUM , SOLID 1 Helium , Solid
Helium was first solidified at the famous Kamerlingh Onnes low-temperature physics laboratories in Leiden by W. H. Keesom [1] on June 25, 1926. The initial experiments by Sir Francis Simon at Oxford University and by Keesom and their collaborators focused on the melting curve, the specific heat, and the thermal conductivity of solid helium as a test of our early understanding of solids. These m...
متن کاملNonlinear elastic stress response in granular packings.
We study the nonlinear elastic response of a two-dimensional material to a localized boundary force, with the particular goal of understanding the differences observed between isotropic granular materials and those with hexagonal anisotropy. Corrections to the classical Boussinesq result for the stresses in an infinite half space of a linear, isotropic material are developed in a power series i...
متن کاملSuperflow in Solid Helium
The small mass and significant zero point motion of solid He make it very different from its conventional counterparts. In the seventies it was suggested that at very low temperatures solid helium might flow like a superfluid while remaining a crystal. This hidden “supersolid” phase was subsequently almost ruled out both by experiments and theoretical calculations. However, in 2004 Kim and Chan...
