I've always been fascinated by how materials break down, especially glasses and polymers that don't have a regular crystal structure. Unlike crystals, where we understand plasticity through things ...

Physicists at UC Santa Barbara, with colleagues at University of Michigan (UM) and The University of Chicago (UChicago), have developed design rules that take advantage of topological defects to ...

The amorphous state of matter is the most abundant form of visible matter in the universe, and includes all structurally ...

We developed a systematic approach to study the topological phases through analyzing the boundary gapless theory. Our main results include: We introduce the twist defect in 2+1 dimensional topological ...
