Polarization squeezing and new states of light in quantum optics

, 1994
The concept of squeezing is discussed for multimode quantum light beams with the consideration of polarization using the polarization gauge SU (2) invariance of free electromagnetic fields. We separate the polarization degrees of freedom from other ones,

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

InfoMat
The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible hand—nanoscale structures that sculpt light itself.

The role of histohematologic barriers and the possibility of using polarization biomedical optics methods in the diagnosis of autoimmune thyroiditis

Mìžnarodnij Endokrinologìčnij Žurnal
Background. Violation of the integrity of the histohematologic barriers (blood-brain, blood-testis, blood-ocular, blood-labyrinth, blood-thyroid) leads to autoimmune damage to these organs.

Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

Advanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Markerless 3D pose estimation system for highly reflective aquatic environments using multi-view polarization imaging and dual-physics constrained network (DP-CRN)

Journal of King Saud University: Computer and Information Sciences
The three-dimensional pose measurement of water sports holds significant value for competitive training and sports injury prevention. However, the coupling interference induced by water surface specular reflection and human wet body surface highlights ...

PHYSICAL SPACE AND ABSTRACT SPACES—Klein Space, Poincaré Space and the Stereographic Projection

Photonics
In this paper we compare the rotation of a rigid body in the real three-dimensional Euclidean space E3 and its representation in the complex plane (Klein space), on one hand, with the transformation of polarization states of light (SOPs) by the phase ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.
