“Topological structure and dynamics of three-dimensional active nematics” appears on the cover of Science

Our work on topological defects in 3D active nematics has been published in Science! Working with the Dogic Lab and several other collaborators, we showed that the bulk version of active nematics (which are usually studied in quasi-2D confinement) are replete with morphing topological defect lines. Among these lines, the “fundamental excitations” are topologically neutral disclination loops, which are continually appearing and self-annihilating throughout the system.
