Luttinger Liquid in the Core of a Screw Dislocation in Helium-4
Monte carlo simulation hexagonal shaft screw crystals superfluids screw dislocation
2014/12/20
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...
Binding of a 3He Impurity to a Screw Dislocation in Solid 4He
Based on simulation the probability density solid atom the nucleus
2014/12/19
Using first-principles simulations for the probability density of finding a 3He atom in the vicinity of the screw dislocation in solid 4He, we determine the binding energy to the dislocation nucleus E...
