چکیده

A theoretical framework is developed for scattering of scalar radiation from stationary, three-dimensional media with correlation functions potentials obeying $\mathcal{PT}$ symmetry. It illustrated that, unlike in deterministic $\mathcal{PT}$-symmetric media, its stationary generalization involves two mechanisms leading to symmetry breaking the statistics scattered radiation, one stemming complex-valued medium realizations and other degree medium's correlation.

Semiquantitative scattering theory of amorphous materials

It is argued that the topological disorder in a small region of an amorphous solid can be described by the local strain field related to the local reference crystal. A localized state spread only in one distorted region can be viewed as the consequence of superposition among some Bloch waves and its scattering waves caused by the disorder. A semiclassical approximation is used to calculate the ...

Effective field theory contribution to charge symmetry breaking NN scattering

The effect of isospin breaking pion s-wave rescattering is included in elastic NN scattering at low energies using effective field theory. Although this mechanism gave a large contribution to charge symmetry breaking in np → dπ, the effect is rather small in pp vs. nn scattering parameters and in the H-He binding energy difference. This smallness is caused by large cancellation of the up-down q...

Terahertz scattering by granular composite materials: An effective medium theory

Terahertz (THz) spectroscopy and imaging have emerged as important tools for identification and classification of various substances, which exhibit absorption characteristics at distinct frequencies in the THz range. The spectral fingerprints can potentially be distorted or obscured by electromagnetic scattering caused by the granular nature of some substances. In this paper, we present THz tim...
