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 ...

From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

Advanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals

Advanced Functional Materials, EarlyView.
Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

CFT_{D} from TQFT_{D+1} via Holographic Tensor Network, and Precision Discretization of CFT_{2}

Physical Review X
We show that the path integral of conformal field theories in D dimensions (CFT_{D}) can be constructed by solving for eigenstates of a renormalization group (RG) operator following from the Turaev-Viro formulation of a topological field theory ...

Massless spectra and gauge couplings at one-loop on non-factorisable toroidal orientifolds

Nuclear Physics B, 2018
So-called ‘non-factorisable’ toroidal orbifolds can be rewritten in a factorised form as a product of three two-tori by imposing an additional shift symmetry. This finding of Blaszczyk et al.

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Quantum criticality of quasi one-dimensional topological Anderson insulators [PDF]

, 2014
We present an analytic theory of quantum criticality in the quasi one-dimensional topological Anderson insulators of class AIII and BDI. We describe the systems in terms of two parameters (g,χ) representing localization and topological properties ...
