Spin‐Orbit Photonics with Potato Starch Lenses
Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,

Orientable quadratic equations in wreath products [PDF]
In this paper we study the complexity of solving orientable quadratic equations in wreath products $A\wr B$ of finitely generated abelian groups. We give a classification of cases (depending on genus and other characteristics of a given equation) when the problem is computationally hard or feasible.

Highly Efficient Upconverted Fluorescence from Coulombically Assembled Ion Pair
A dicationic Os(II) complex paired with two monoanionic fluorophores is designed to enable highly efficient triplet–triplet annihilation upconversion, achieving a remarkable upconverted fluorescence quantum yield of 13% at 785 nm excitation with a record‐low threshold intensity of 5.9 mW cm⁻2, attributed to diffusion‐free acceleration of energy ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

On rank 3 quadratic equations of Veronese varieties [PDF]
This paper studies the geometric structure of the locus $\Phi_3 (X)$ of rank $3$ quadratic equations of the Veronese variety $X = \nu_d (\mathbb{P}^n)$. Specifically, we investigate the minimal irreducible decomposition of $\Phi_3 (X)$ of rank $3$ quadratic equations and analyze the geometric properties of the irreducible components of $\Phi_3 (X ...

Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...
