Advanced Optical Materials, EarlyView.Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

The conundrum of stock versus bond prices
, 2003 In a general way, stock and bond prices do not display any significant correlation. Yet, if we concentrate our attention on specific episodes marked by a crash followed by a rebound, then we observe that stock prices have a strong connection with ...

Switchable Terahertz Beam Steering with Near‐Perfect Ordinary Transmission
Advanced Photonics Research, EarlyView.This study introduces a reconfigurable metasurface that enables switchable terahertz beam steering upon actuation by a global temperature change. At room temperature, it achieves a true “OFF” state with nearly 100% transmission, behaving as if the metasurface is not present, thereby not distorting incoming light.

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective
Advanced Photonics Research, EarlyView.This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Advanced Theory and Simulations, EarlyView.A side‐view schematic illustrating intra‐ and inter‐band optical recombination processes in quantum wells, highlighting applications that depend on carrier dynamics and recombination lifetimes, such as lasers, photodetectors, and solar cells. Abstract Radiative lifetime (RT) on the picosecond to femtosecond scale plays a key role in enabling ultrafast ...

Design of CsSnBr3/Ga2O3 Hybrid Photodetectors for High UV Selectivity and Bifacial Usage
Advanced Theory and Simulations, EarlyView.A numerical study investigates a lead‐free CsSnBr3/Ga2O3 p–n heterojunction photodetector, analyzing its electrical and optoelectronic performance. High illumination‐to‐dark current ratios and rectification are achieved. The device operates in self‐powered, bifacial, solar‐blind, and UV–Vis modes with strong responsivity and detectivity.
