Topological defects appear in symmetry breaking phase transitions and are ubiquitous
throughout Nature. As an ideal testbed for their study, defect configurations in nematic liquid …

Lattice kirigami, ultralight metamaterials, polydisperse aggregates, ceramic nanolattices,
and 2D atomic materials share an inherent structural discreteness, and their material …

An escaped radial director profile in a nematic liquid crystal cell can be transformed into a
pair of strength m=+ 1/2 surface defects (and their associated disclination lines) at a …

Topological phases are stable configurations of matter in 2-dimensions (2D) formed via
spontaneous symmetry breaking. These play a crucial role in determining the system …

A patterned surface defect of strength m=+ 1 and its associated disclination lines can
decompose into a pair of surface defects and disclination lines of strength m=+ 1/2. For a …

Controlling polymorphism in ordered molecular solids through manipulation of processing
method has been rarely addressed despite its significance in creating assembled molecular …

A substrate was patterned with two pairs of half-integer strength topological defects,(+ 1/2,+
1/2) and (+ 1/2,− 1/2). In a sufficiently thick cell, a disclination line runs in an arch above the …

Understanding geometric frustration of ordered phases in two-dimensional condensed
matter on curved surfaces is closely related to a host of scientific problems in condensed …

We investigate the dynamics of an active particle in two-dimensional spherical crystals,
which provide an ideal environment to illustrate the interplay between active particles and …

Elucidating long-range interaction guided organization of matter is a fundamental question
in physical systems covering multiple length scales. Here, based on the hexagonal disk …
