Experimental determination of correlations between spontaneously formed vortices in a superconductor
Daniel Golubchik, Emil Polturak, Gad Koren +2
We have imaged spontaneously created arrays of vortices (magnetic flux quanta), generated in a superconducting film quenched through its transition temperature at rates around $10^…
The influence of boundaries on high pressure melting experiments
V. Sorkin, E. Polturak, Joan Adler
At low pressure, free surfaces play a crucial role in the melting transition. Under pressure, the surface of the sample is acted upon by some pressure transmitting medium. To exami…
Path Integral Monte Carlo study of phonons in the bcc phase of He
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 in the bcc phase at a finite temperature of T = 1.6 K and…
Molecular dynamics study of melting of a bcc metal-vanadium II : thermodynamic melting
V. Sorkin, E. Polturak, Joan Adler
We present molecular dynamics simulations of the thermodynamic melting transition of a bcc metal, vanadium using the Finnis-Sinclair potential. We studied the structural, transport…
Observation of a new excitation in bcc solid 4He by inelastic neutron scattering
T. Markovich, E. Polturak, J. Bossy +1
We report neutron scattering measurements of the phonons in bcc solid 4He. In general, only 3 accoustic phonon branches should exist in a monoatomic cubic crystal. In addition to t…
