We review the interactions and dynamics of topological defects in liquid crystals (LCs) in
quasi-two-dimensional (2D) geometries. Such spatial restrictions can be realized in thin …

Topological line defects are ubiquitous in nature and appear at all physical scales, including
in condensed matter systems, nuclear physics, and cosmology. Particularly useful systems …

Mechanically quenching a thin film of smectic-C liquid crystal results in the formation of a
dense array of thousands of topological defects in the director field. The subsequent rapid …

Machine learning techniques have been developed to identify inclusions on the surface of
freely suspended smectic liquid crystal films imaged by reflected light microscopy. The …

We investigate the emergence of orientational order among+ 1/2 disclinations in active
nematic liquid crystals. Using a combination of theoretical and experimental methods, we …

Disclinations or disclination clusters in smectic C freely suspended films with topological
charges larger than one are unstable. They disintegrate, preferably in a spatially symmetric …

We study the dynamics of topological defects in continuum theories governed by a free
energy minimization principle, building on our recently developed framework (Romano et al …

Point-like topological defects are singular configurations that manifest in and out of various
equilibrium systems with two-dimensional orientational order. Because they are associated …

In this paper we study the static structure and the dynamics of topological defects associated
with isotropic droplets in nematic environment. Investigations were made in confined …

Freely suspended films in the smectic C phase are excellent templates for the study of
topological defect dynamics. It is well known that, during the annihilation of a pair of …
