Morphological stability of a crystal with respect to arbitrary boundary perturbations
L. M. Martyushev, Сергей Владимирович Серебренников · Technical Physics Letters · 2006
The morphological stability of a growing round crystal with respect to harmonic perturbations of arbitrary amplitudes has been studied. The critical crystal size with respect to stable growth decreases with increasing amplitude of perturbations and tends to a value that was previously analytically determined proceeding from the principle of maximum entropy production. This result offers new important evidence for the validity of a hypothesis concerning the possibility of using entropy production instead of a thermodynamic potential in the analysis of nonequilibrium phase transitions.
