The Polarizability Vector: A Polarimetric Observable for Characterizing Anisotropic Nanoparticles

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
We find an overlooked observable in Nanophotonics that characterizes the optical response of anisotropic nanoparticles from simple polarimetry measurements. ABSTRACT The optical properties of anisotropic nanoparticles (NPs) are often characterized by two principal components of their polarizability tensor.

Molecular Engineering for Enhanced Second‐Order Nonlinear Response in Spontaneously‐Oriented Evaporated Organic Films

Advanced Optical Materials, Volume 14, Issue 7, 16 February 2026.
Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.

Shedding new light on the Crab with polarized X-rays

Scientific Reports, 2017
Strong magnetic fields, synchrotron emission, and Compton scattering are omnipresent in compact celestial X-ray sources. Emissions in the X-ray energy band are consequently expected to be linearly polarized. X-ray polarimetry provides a unique diagnostic
