Photonic Floquet–Bloch Oscillations Dominated by Floquet Gauge

open access: yesLaser &Photonics Reviews, EarlyView.
A new type of Bloch oscillations (namely, asymmetric Floquet–Bloch oscillations) whose evolution is biased along the evolution dimension is proposed and visually observed. The Floquet gauge can determine the light broadening to be biased toward the first or second half of the period. These findings reveal a new mechanism for wave packet revival and may

Cylindrical Vector Beam Multiplexing based on All‐Dielectric Fiber Meta‐Tips Enabling High‐Capacity Bidirectional Optical Communication

open access: yesLaser &Photonics Reviews, EarlyView.
Cylindrical vector beam (CVB) multiplexing offers a viable solution to channel capacity, integration, and unidirectional transmission challenges in fiber‐rich sixth‐generation backbone networks. An all‐dielectric fiber meta‐tip‐enabled CVB multiplexing system is proposed and demonstrated, providing high‐capacity, bidirectional optical interconnects and

MEMS‐Tunable Bilayer Plasmonic Metasurfaces for Dynamic Vortex Wave Plates

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a MEMS‐tunable bilayer metasurface for dynamic vortex wave plates at near‐infrared wavelengths. By electrically tuning the separation between the BMS and the MEMS mirror, the device enables reconfigurable switching between l = 2 and l = −1 vortex modes, achieving >80% polarization conversion efficiency, fast response time (9 µs), and

A Perspective of Multi‐Reflecting TOF MS

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Hybrid Stochastic Simulation for Accelerated Modeling of Free Radical and Degenerative Transfer Polymerization

open access: yesMacromolecular Theory and Simulations, EarlyView.
This study presents a hybrid stochastic simulation algorithm for modeling free radical and degenerative transfer polymerization. The method uses Poisson‐based bulk updates for frequent propagation/transfer events while maintaining discrete treatment of critical initiation/termination steps.

Orthostatic Tremor Is Evoked by Muscle Load Without the Need for Orthostatic Position

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Primary orthostatic tremor (POT) is a rare movement disorder characterized by a high‐frequency tremor and a considerable feeling of unsteadiness. People with POT are significantly affected in their daily activities and have reduced quality of life.
