Ginzburg-Landau theory of the bcc-liquid interface kinetic coefficient
Abstract
We extend the Ginzburg-Landau (GL) theory of atomically rough bcc-liquid interfaces [Wu et al., Phys. Rev. B 73, 094101 (2006)PRBMDO1098-012110.1103/PhysRevB.73.094101] outside of equilibrium. We use this extension to derive an analytical expression for the kinetic coefficient, which is the proportionality constant μ(n̂) between the interface velocity along a direction n̂ normal to the interface and the interface undercooling. The kinetic …
