Mermin topological defects

WebTopological defects are critical to understanding a wide range of physical phenomena because they can carry energy and momentum [1]. Moreover, they are not only stable against small external perturbations but they also cannot easily decay or be un-entangled since they cannot be continuously transformed into a “trivial” form.
