Nanophotonics, Volume 15, Issue 9, 13 May 2026.Structured illuminations can unlock hidden quasi‐BIC modes in Fano‐resonant metasurfaces, enhancing the sensitivity to nanoscale perturbations. By analyzing the eigenmode spectrum of a dielectric metasurface and applying information theory, tailored wavefronts can be engineered that selectively excite otherwise inaccessible modes.

Optical Skyrmions Modulation Based on Polarization Helicity
Nanophotonics, Volume 15, Issue 9, 13 May 2026.The polarization helicity represents the global twisted property of the polarization state distribution, it can be used to modulate the spin skyrmion texture in the tight focusing of the radially polarized vortex light. By adjusting the polarization helicity of incident field, the Néel‐Bloch‐Néel transition of the spin skyrmion texture can be realized,

Squeezing-induced quantum-enhanced multiphase estimation
Physical Review ResearchWe investigate how squeezing techniques can improve the measurement precision in multiphase quantum metrology. While these methods are well studied and effectively used in single-phase estimations, their usage in multiphase situations has yet to be ...

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors
Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...
