Revealing the Resonant Physics of Open Photonic Time Crystals
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Theory of Supercritical Coupling and Generalized Bound States in the Continuum
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Propagation loss in slow light photonic crystal waveguides
The field of nanophotonics is a major research topic, as it offers potential solutions to important challenges, such as the creation of low power, high bandwidth interconnects or optical sensors.

This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities
Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

Magnetically Decoupled Janus Bound States in the Continuum for Chirality–Topology Control
This article demonstrates the Janus BICs, which are bi‐layer photonic crystal (PhCs) structures composed of C3v and magneto‐optical C6v symmetry slabs. It offers a unique platform for independent controlling chirality and topological charge, which successfully realizes the decoupling of topological charge and chirality.
