Chiral π Domain Walls Composed of Twin Half-Integer Surface Disclinations in Ferroelectric Nematic Liquid Crystals

This paper reveals that π\pi domain walls in ferroelectric nematic liquid crystals are composed of twin half-integer surface disclinations that partition subdomains of opposite chirality, establishing a hierarchical topological structure that dictates a two-step mechanism for field-driven polarization switching.

Non-universal localization transition in the quantum Hall effect probed through broken-symmetry states of graphene

By systematically measuring localization lengths in broken-symmetry quantum Hall states of graphene, this study reveals significant non-universality and deviations from standard scaling, which are successfully explained by a model involving the co-existence of localized states from two successive sub-Landau levels.

Non-local synchronization of continuous time crystals in a semiconductor

This paper demonstrates that spatially remote, auto-oscillating electron-nuclear spin systems in a semiconductor can achieve non-local synchronization over distances up to 40 μm via electron spin diffusion, thereby establishing mesoscopic phase coherence and enabling stable collective motion in distributed spin networks.

Theoretical investigation of two-dimensional semiconductor nanoribbons and nanoparticles for tailored light--matter interactions

This theoretical study investigates the optical response of 2D semiconductor nanostructures, revealing that while the localized nature of excitons in nanoribbon arrays limits geometric tunability, coating spherical nanoparticles with these materials offers a superior platform for achieving controllable light-matter interactions through hybridization.
