摘要:In the this talk I will introduce my research work on fractional phase-field/phase-field crystal modeling: analysis, approximation, and pattern formation. I will first introduce a fractional Cahn-Hilliard model, which preserves mass and indeed reduces the energy. The well-posedness is established, and we show that the solution is uniformly bounded in the L∞ sense and other properties. Then I will introduce a fractional phase-field crystal (PFC) model which gives a markedly superior fit to experimental measurements of the structure factor than the classical PFC for a number of crystalline materials. The fractional PFC model retains the salient feature of the PFC model, and, in addition, provides better predictions for the grain boundary energy at larger values of the mismatch angles.
