Empowering material defect research with machine learning

: Material defects govern the performance limits, degradation pathways, and service lifetimes of functional and structural materials, yet their predictive modeling remains difficult because local electronic reconstruction, long-range interactions, rare kinetic events, and finite-temperature effects are coupled across s...

Automated surrogate-assisted inverse design of polarization-tailored optical transfer functions in nonlocal metasurfaces.

Nonlocal metasurfaces offer a compact platform for analog optical computing, but the inverse design of polarization-resolved optical transfer functions (OTFs) remains challenging because structural parameters are strongly coupled to angle- and polarization-dependent responses. Here, we present a surrogate-assisted inve...
