Reconstructing Three‐Dimensional Optical Anisotropy with Tomographic Müller‐Polarimetric Microscopy
Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

Au‐Pd super‐heterostructures not only retard the damping of chiroptical response but also enantio‐selectively enhance photocatalysis, thanks to the chiral electromagnetic field and chiral hot electrons. Abstract Seed‐mediated growth provides an efficient way to produce chiral hybrid nanocrystals, mainly benefitting from the recent successful synthesis ...

Protected Chaos in a Topological Lattice
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Achromatic 3D Multi‐Color Orbital Angular Momentum Holography
This work presents an achromatic 3D multicolor orbital angular momentum (OAM) holography based on spatial multiplexing. By integrating wavelength‐specific lens functions onto monochromatic Fourier OAM‐dependent holograms and high‐resolution spatial discretization and interleaving via two‐photon lithography (TPL), the approach addresses axial chromatic ...

The expansive design space of advanced metasurfaces, particularly those with multiple degrees of freedom (MDOF), renders traditional design methods less effective. A physics‐driven intelligent design is proposed for MDOF metasurfaces, which integrates physical knowledge into neural networks, enhancing interpretability and computational efficiency. This
