A Monte-Carlo Approach to Zero Energy Quantum Scattering [PDF]
, 1995 Monte-Carlo methods for zero energy quantum scattering are developed. Starting from path integral representations for scattering observables, we present results of numerical calculations for potential scattering and scattering off a schematic $^4 \rm He $

Scattering and inverse scattering on ACH manifolds [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2008 We study scattering and inverse scattering theories for asymptotically complex hyperbolic manifolds. We show the existence of the scattering operator as a meromorphic family of operators in the Heisenberg calculus on the boundary, which is a contact manifold with a pseudohermitian structure.

Cold and Thermal Neutron Single Grating Dark-Field Imaging Extended to an Inverse Pattern Regime
Applied Sciences, 2022 Neutron dark-field imaging is a powerful tool for the spatially resolved characterization of microstructural features of materials and components. Recently, a novel achromatic technique based on a single absorption grating for the concurrent measurement ...

Neutrino Opacity I. Neutrino-Lepton Scattering [PDF]
, 1964 The contribution of neutrino-lepton scattering to the total neutrino opacity of matter is investigated; it is found that, contrary to previous beliefs, neutrino scattering dominates the neutrino opacity for many astrophysically important conditions.

Asymmetric propagation of spoof surface plasmons along doubly corrugated metal surfaces
AIP Advances, 2020 Spoof surface plasmons (SSPs) on the doubly corrugated metal surfaces can find a variety of applications, such as waveguides, filters, sensors, communications, and other high-performance active devices in terahertz (THz) and microwave bands.

Dispersion Theory of Surface Plasmon Polaritons on Bilayer Graphene Metasurfaces
Nanomaterials, 2022 Surface plasmon polaritons (SPPs) on the graphene metasurfaces (GSPs) are crucial to develop a series of novel functional devices that can merge the well-established plasmonics and novel nanomaterials.

Scattering properties of anti-parity-time symmetric non-Hermitian system [PDF]
Phys. Rev. A 98, 022117 (2018), 2018 We investigate the scattering properties of an anti-parity-symmetric non-Hermitian system. The anti-parity-symmetric scattering center possesses imaginary nearest-neighbor hoppings and real onsite potentials, it has been experimentally realized through dissipative coupling and frequency detuning between atomic spin waves.

Inherent Relations among the Three Representations of Radar Target Angular Glint (in English)
Leida xuebao, 2014 Based on ElectroMagnetic (EM) theory and the monopulse radar angle measurement principle, the formulae of angular glint for complex target are proposed and generally applied to tackling practical problems.
