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...
Molecular-dynamics Simulations of Stacking-fault-induced Dislocation Annihilation in Pre-strained Ultrathin Single-crystalline Copper Films
Molecular dynamics dynamic deformation metal structure
2014/12/19
We report results of large-scale molecular-dynamics (MD) simulations of dynamic deformation under biaxial tensile strain of pre-strained single-crystalline nanometerscale- thick face-centered cubic (f...
Entropic Effect on the Rate of Dislocation Nucleation
Entropic Effect the Rate of Dislocation Nucleation
2010/11/18
Dislocation nucleation is essential to our understanding of plastic deformation, ductility and
mechanical strength of crystalline materials. Molecular dynamics simulation has played an important role...

The Relation Between Dislocation Density and Crystal Crosscut in b-Sn Grown by Modified Bridgman Method
Dislocation Density Crystal Crosscut b-Sn Grown
2010/4/19
Crystals b-Sn are grown from ingots of 99.99% purity by modified Bridgman method under 10-3 torr pressure and oriented by Laue back reflection method. The relation between crystal crosscut and disloca...
