Fcc-bcc transition for Yukawa interactions determined by applied strain deformation.
Calculations of the work required to transform between bcc and fcc phases yield a high-precision bcc-fcc transition line for monodisperse point Yukawa (screened-Coulomb) systems. Our results agree qualitatively but not quantitatively with recently published simulations and phenomenological criteria for the bcc-fcc transition. In particular, the bcc-fcc-fluid triple point lies at a higher inverse screening length than previously reported.
