Combinatorial zeta functions counting triangles

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract In this paper, we compute special values of certain combinatorial zeta functions counting geodesic paths in the (n−1)$(n-1)$‐skeleton of a triangulation of an n$n$‐dimensional manifold. We show that they carry a topological meaning. As such, we recover the first Betti and L2$L^2$‐Betti numbers of compact manifolds, and the linking number of ...

Achromatic Petal‐Shaped Beam Generation and Information Encoding Based on Perfect Vortex Beam

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Based on petal‐shaped beams with controllable topological charge, size, and rotation angle, this work employs a spatially multiplexed all‐dielectric TiO2 transmissive array to numerically achieve achromatic petal‐shaped beams at three wavelengths: 480 nm, 530 nm, and 630 nm. Leveraging their unique intensity distribution and rotational characteristics,

Customizable Fully Structured Vector Trajectory Beams in the Focal Plane via a Single‐Layer Metasurface

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work introduces a unique class of structured light—trajectory beams—where all degrees of freedom evolve dynamically along the predefined trajectory. By employing computer‐generated holography, single‐layer metasurfaces achieve the complete decoupling of trajectory shape and the distributions of amplitude, phase, and polarization along the path ...
