Mechanically‐Gated Stochastic Resonance for All‐Optical Acoustic Sensing in Noisy Environments

Advanced Science, EarlyView.
A mechanically‐gated stochastic resonance (MGSR) sensing system is demonstrated, wherein stochastic resonance is enabled by an all‐optical bistable fiber Bragg grating feedback loop and gated by mechanical resonance. Under ambient noise, the system generates bistable outputs satisfying the Kramers escape‐rate condition, yielding signal‐to‐noise ratio ...

Colossal Modulation of Mechanical Resonance with temperature in single‐Crystalline SrTiO3 Microbridges Integrated on Silicon

Advanced Electronic Materials, EarlyView.
The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

Perspective: Quantum Computing on Magnetic Racetrack

Advanced Electronic Materials, EarlyView.
Magnetic domain walls emerge as mobile qubits on quantum racetracks, where chirality encodes quantum information and current‐driven motion enables flying‐qubit functionality. This Perspective outlines the physical principles, gate mechanisms, material requirements, and experimental roadmap for realizing scalable quantum computing with magnetic textures,

A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.
