Grain Boundary Diffusion in Yukawa Crystals
Matthew E. Caplan, Nevin T. Smith, Dany Yaacoub +3
We present calculations of diffusion coefficients in grain boundaries in Yukawa crystals for astrophysics. Our methods follow from our recent work calculating diffusion coefficient…

No Evidence of Anomalous Diffusion in Yukawa Crystals
Matthew E. Caplan, Dany Yaacoub
Diffusion in Yukawa crystals is stochastic due to the thermally activated formation of vacancy-interstitial pairs, which have poor statistics in simulations. This makes it difficul…
