A Model for Dipole Electromagnetic Form Factors [PDF]

Progress of Theoretical Physics, 1971
Summary: A model of the electromagnetic form factor of the scalar \(\pi\) meson is discussed in which the \(\pi\) meson is a bound state of scalar nucleon-antinucleon system. Starting from an exact integral representation of the form factor, which is well defined in a space-like region of the momentum transfer squared, \(q^2\), an analytic continuation

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.
