“Complex crystal structures in hard and soft condensed matter”


Materials’ properties crucially depend on their structural features, and functional, novel materials can be designed based on the choice of specific geometries. Complex structures have been observed on the atomic scale for decades and their origin, e.g., in intermetallic systems, has yet to be explained [1,2]. While most crystal structures found in soft matter systems have thus far been very simple, intricate geometries occur more frequently now as particle fabrication technologies become increasingly versatile (e.g., [3]). In order to understand why and how complex structures form – across various length scales –, we study the self-assembly and phase behavior of particles interacting via simple, tunable pair potentials. These systems assemble into a wide range of crystal structures, from simple sphere packings to complex structures with large unit cells (and even quasicrystals [4]), and with various global symmetries and local motifs. By investigating structural trends among these simple model systems, we hope to describe and understand how disparate atomic and soft-matter systems form a common set of complex crystal structures, and move toward structure prediction and materials design in the future.


Dr. Julia Dshemuchadse received her Diploma degree in Physics from TU Dresden, Germany, in 2008. She earned her PhD in 2013 in Materials Science from ETH Zurich, Switzerland, where she investigated building principles of complex intermetallic compounds under the guidance of Prof. Walter Steurer. In 2015, Julia joined the group of Prof. Sharon C. Glotzer at the University of Michigan, Ann Arbor, on a postdoctoral fellowship from the Swiss National Science Foundation, where she is researching soft-matter self-assembly behavior by means of numerical simulations. She earned the Max-von-Laue award from the German Crystallographic Society in 2015 and an Outstanding Postdoctoral Fellow Award of the University of Michigan in 2016.
