Divergent Electrochemical Behaviors of O2 and O3 Phases in Li‐Rich Layered Oxides

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Lithium‐ion batteries (LIBs) have dominated the landscape of electrochemical energy storage for decades. The growing market demands for higher energy densities are pushing against the limitations of conventional cathode materials. Li‐rich layered oxides (LLOs) present a promising path forward by harnessing both cationic and anionic redox ...

Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

Small, Volume 22, Issue 47, 21 August 2026.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Increasing of Q Factor of Quasi‐Bound States in the Continuum With Increased Asymmetry Parameter in a Silicon Metasurface Array

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Quasi‐bound states in the continuum (qBICs) can support resonances with high quality (Q) factor. Traditionally, maintaining a high Q factor requires a small α, which brings significant challenges for nanofabrication. In contrast, our study finds an increase in the Q factor with increasing of α in a metasurface array composed of Si blocks with circular ...

The acoustic Dirac equation as a model of topological insulators

Frontiers in Acoustics
The dynamical equations of motion for a discrete, one-dimensional harmonic chain with side restoring forces are analogous to the relativistic Klein–Gordon equation. Dirac factorization of the discrete Klein–Gordon equation introduces two equations with time reversal (T) and parity (P) symmetry-breaking conditions.

Three-dimensional acoustic Chern insulators with arbitrary Chern vectors

Physical Review Research
The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phases of three-dimensional (3D) Chern insulators. Such a vectorial generalization extends the applicability of Chern-type bulk-boundary

Coupled order parameters and photoinduced domain walls in the charge density wave of (TaSe4)2I

npj Quantum Materials
The charge density wave in (TaSe4)2I has drawn much attention recently as a controversial candidate for an axion insulator where the CDW breaks the chiral symmetry of the Weyl semimetal.

Dislocation defect states in acoustic quadrupole topological insulators

Acta Physica Sinica
Quadrupole topological insulator (QTI) is the first proposed higher-order topological phase of matter with quantized quadrupole moment but zero dipole moment. The QTI has expanded widely the traditional bulk-boundary correspondence, thereby the lower-dimensional topological boundary state can be observed.
