Fcc-bcc transition for Yukawa interactions determined by applied strain deformation

R. S. Hoy and M. O. Robbins, Phys Rev E, 69, 056103 (2004).

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.
