Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Hydride Nitrides: Crystal Structure Redetermination of LiSr2H2N and the Isostructural LiBa2H2N
The quaternary hydride nitrides LiSr2H2N and LiBa2H2N are obtained in a non‐centrosymmetric crystal structure, different from previous reports. Crystal growth of the honey‐ and pale‐yellow compounds and essentially single phase synthesis is successful using alkali metal flux. The resulting fully ordered structures do not account for a structural reason

Dynamic Multifunctional Metasurfaces Based on Passive Cascade Structure
A dynamic multifunctional metasurface is proposed in this paper. Unlike mainstream multifunctional metasurface based on programmable metasurfaces, it consists of two passive metasurfaces, presenting a significant cost advantage. By controlling the displacement, different functions such as beam steering, focusing, and OAM wave generation can be realized

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.
