Density-field Modeling of Material Microstructures and Dynamics: Advances and Challenges

One of the long-lasting challenges in the study of advanced materials is how to effectively tackle the vast complexity of the system that is of nonequilibrium nature and involves multiple spatial and temporal scales. Of particular importance is the bridging between material microstructural details and mesoscopic characteristics such as surface patterns or interfacial structures, for which much of recent theoretical effort has been put on the development of novel density-field based approaches that incorporate different scales. In this talk I will discuss some recent advances in this field for modeling material microstructures and dynamics, particularly a rapidly developing area based on this type of multi-scale approach, i.e., the phase field crystal modeling, and some of its ongoing challenges. Sample topics include the emergence of ordering phases, the control of 2D structure or pattern chirality and chiral elastic properties, structures and collective dynamics of topological defects in binary 2D materials such as h-BN, and if time permits, the interface lattice pinning effect during material growth due to the coupling between micro and meso spatial scales.

Dr. Zhi-Feng Huang is an associate professor of physics at Wayne State University, working in the area of theoretical condensed matter physics and modeling of solid and soft complex materials. He obtained his B.Sc. and Ph.D. degrees in Physics from Tsinghua University, China, and was a recipient of the US National Science Foundation CAREER Award and Wayne State Career Development Chair Award.
