Steering visible Dyakonov surface waves at the hyperbolic metasurface
, 2021 Dyakonov surface wave existing at the interface with anisotropy offers a promising way of guiding light in two-dimension with almost no loss. However, predicted decades ago, the experimental demonstration of the Dyakonov surface wave seems always challenging for the weak anisotropic indices from the natural materials.

Direct Observation of Intrinsic Spin–Layer Coupling and Robust Valley Polarization in Bilayer MoS2
Small Science, Volume 5, Issue 11, November 2025.This study experimentally demonstrates finite and even enhanced circular polarization in bilayer MoS2, despite its centrosymmetric 2H stacking, across all temperatures. The degree of circular polarization exceeds that of monolayers, attributed to spin–layer coupling and suppression of spin‐flip processes.

Oblique surface waves at an interface of metal-dielectric superlattice and isotropic dielectric
, 2011 We investigate the existence and the dispersion characteristics of surface waves that propagate at an interface between metal-dielectric superlattice and isotropic dielectric.

Small Structures, Volume 6, Issue 11, November 2025.Breaking the structural symmetry of devices is a crucial design strategy that endows terahertz (THz) detectors with novel operating mechanisms and unique characteristics. This study provides an in‐depth discussion on symmetry‐breaking‐induced phenomena, novel asymmetric structures, and dominant detection mechanisms.

Stone dust in endourology: a systematic review of its definition, management, and clinical impact
BJU International, Volume 136, Issue 2, Page 185-197, August 2025.Objective To evaluate and synthesise the existing literature on stone dust (DUST) in endourology, focusing on its definition, creation methods, and removal techniques. Methods A comprehensive electronic literature search was conducted using the PubMed/Medline, Web Of Science, and Embase databases to identify reports published until October 2024.

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals
Advanced Science, Volume 12, Issue 27, July 17, 2025.Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

Optimizing Phononic Crystal Waveguides for Enhanced Surface Acoustic Wave Confinement
physica status solidi (b), Volume 262, Issue 7, July 2025.A phononic crystal consisting of periodic arrays of nanofabricated holes on a surface can form a metamaterial‐like layer with properties different from the host material. Exploiting these surface properties, an optimized waveguide geometry is designed for surface acoustic waves using twofold elliptical cylinder inclusions to create a slow region that ...

Quantum Interference Controls the Electron Spin Dynamics in n-GaAs
, 2018 Manifestations of quantum interference effects in macroscopic objects are rare. Weak localization is one of the few examples of such effects showing up in the electron transport through solid state.
