Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology
Advanced Photonics Research, EarlyView.This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Spectral pruning of fully connected layers
Scientific Reports, 2022 Training of neural networks can be reformulated in spectral space, by allowing eigenvalues and eigenvectors of the network to act as target of the optimization instead of the individual weights.

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective
Advanced Photonics Research, EarlyView.This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Realization of Spin‐locked Acoustic Helical Landau Levels in both Hexagonal and Square Lattices
Advanced Science, EarlyView.Acoustic helical Landau levels rooted in quantum spin Hall systems are achieved by linearly increasing the local bandgap through the lifting of the double Dirac cone in acoustic crystals. Large‐area conveyance of acoustic energy facilitated by these helical Landau levels is demonstrated.

Benefits of Open Quantum Systems for Quantum Machine Learning
Advanced Quantum Technologies, EarlyView., 2023 Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.
