Codimension-2 defects and higher symmetries in (3+1)D topological phases
SciPost Physics, 2023 (3+1)D topological phases of matter can host a broad class of non-trivial topological defects of codimension-1, 2, and 3, of which the well-known point charges and flux loops are special cases.

ON TOPOLOGICAL DEFECTS AND COSMOLOGICAL CONSTANT [PDF]
Modern Physics Letters A, 2014 Einstein introduced cosmological constant in his field equations in an ad hoc manner. Cosmological constant plays the role of vacuum energy of the universe which is responsible for the accelerating expansion of the universe. To give a theoretical support, it remains an elusive goal to modern physicists. We provide a prescription to obtain cosmological

Topological defects in conformal field theory [PDF]
, 2023 openThis thesis objective is to characterize the topological defects of a particular two dimensional conformal quantum field theory. Topological defects can be interpreted as generalizations of global symmetries and, between other things, give rise to ...

Quasi-one-dimensional metallic conduction channels in exotic ferroelectric topological defects
Nature Communications, 2021 Ferroelectric topological defects show emerging exotic physical properties, which are important for future nanoelectronic devices. Here, the authors demonstrate conductive metallic conduction channels in two types of topological defects, namely vortex ...

Topology, defects, and topological defects [PDF]
, 2020 The purpose of this Thesis is to theoretically investigate the power of topology on various problems in condensed-matter physics, as well as their possible applications for biological systems. We start the discussions with the so-called Laughlin’s gauge argument, i.e. quantized topological adiabatic transport in the integer quantum Hall cylinder.

Colloquium : disclination loops, point defects, and all that in nematic liquid crystals [PDF]
, 2012 The homotopy theory of topological defects is a powerful tool for organizing and unifying many ideas across a broad range of physical systems. Recently, experimental progress was made in controlling and measuring colloidal inclusions in liquid ...
