Estimating Lab-Quake Source Parameters: Spectral Inversion from a Calibrated Acoustic System

open access: yesSensors
Laboratory acoustic emissions (AEs) serve as small-scale analogues to earthquakes, offering fundamental insights into seismic processes. To ensure accurate physical interpretations of AEs, rigorous calibration of the acoustic system is essential. In this

Extrinsic Limitations of Stealthy Hyperuniform Devices

open access: yesAdvanced Optical Materials, EarlyView.
Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

Bright‐Dark Exciton Splitting in Lead Iodide Perovskite Crystals Accessed via Quantum Beats in Photon Echoes

open access: yesAdvanced Optical Materials, EarlyView.
Understanding exciton fine structure is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization‐sensitive photon‐echo spectroscopy in a magnetic field resolves exciton fine‐structure splittings hidden by inhomogeneous broadening, enabling direct determination of the bright‐dark ...
