Is the surface fluid during surface melting, a study of the surface shear modulus of solid Gallium
Almog Danzig, Ori Scaly, Emil Polturak
Melting of 3D solids is often preceded by a melting of their surface, a distinct process which begins at a temperature lower than the melting temperature. Until now, surface meltin…
Observation of quantum friction in solid 4He
Almog Danzig, Ori Scaly, Emil Polturak
Classical sliding friction is dominated by the slip-stick mechanism, where contacts between two bodies are alternately formed and sheared as the bodies move past each other. When t…
Characterization of the Surface of Moving solid 4He
Ethan Livne, Anna Eyal, Ori Scaly +1
Crystal grains of solid He can move in relation to each other even when embedded inside the solid. In this work, we characterize a macroscopic motion of solid hcp He compos…
Path-integral Monte Carlo study of phonons in the bcc phase of Helium-3
V. Sorkin, E. Polturak, Joan Adler
Using Path Integral Monte Carlo and the Maximum Entropy method, we calculate the dynamic structure factor of solid He-3 in the bcc phase at a finite temperature of T = 1.6 K and a…
Molecular dynamics study of melting of a bcc metal-vanadium I: mechanical melting
V. Sorkin, E. Polturak, Joan Adler
We present molecular dynamics simulations of the homogeneous (mechanical) melting transition of a bcc metal, vanadium. We study both the nominally perfect crystal as well as one th…
Influence of Point Defects on the Shear Elastic Coefficients and on the Melting Temperature of Copper
Amit Kanigel, Joan Adler, Emil Polturak
We present molecular dynamics simulations of the influence of point defects on the shear elastic coefficients of copper. We find that vacancies do not influence these coefficients…
