Key Points

Dislocations in cholesteric materials untie as a result of phase transition dynamics, leading to new configurations.
Phase transitions between normal to superfluid and isotropic to nematic are critical in the untangling processes.
This process can be explained via knot theory, illustrating the complex interactions within these materials.
Understanding these dynamics of vortices and disclinations may have applications in advanced materials science.

Implication

Analysis of phase transitions reveals rewiring of knots and links in cholesteric materials, suggesting new insights into dislocation dynamics.

Abstract

Knotted and linked skeins of vortices and disclinations generated, respectively, by symmetry-breaking normal → superfluid and isotropic → nematic phase transitions are known to untie, by rewiring of their crossings,...
