Spectral broadening from turbulence in multiscale lower hybrid current drive simulations
Nuclear Fusion, 2022 The scattering of lower hybrid (LH) waves due to scrape-off layer filaments is investigated. It is revealed that scattering can account for the LH spectral gap without any ad hoc modification to the wave-spectrum.

Journal of Marine Science and Engineering, 2023 Based on the assumption of linear potential flow theory, the scattering problem of a composite breakwater placed in front of an impermeable back wall is theoretically investigated. The velocity potential in each subregion is found using the eigenfunction

Wave Scattering by a Perforated Duct [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2002 Summary: Recently, a number of linear wave scattering problems have been studied in the context of embedding formulae. Such formulae typically express the solution for any incident wave angle in terms of the solutions corresponding to a finite number of angles; they are of interest from a theoretical point of view and because they lead to significant ...

Simulating Meson Scattering on Spin Quantum Simulators [PDF]
QuantumStudying high-energy collisions of composite particles, such as hadrons and nuclei, is an outstanding goal for quantum simulators. However, preparation of hadronic wave packets has posed a significant challenge, due to the complexity of hadrons and the ...

Quantum Scattering Theory in a Discrete Representation
EPJ Web of Conferences, 2016 The approach to solving few-body scattering problems in a discrete representation of the stationary wave packets is described briefly. By projecting into the wave-packet basis, all the operators and wave functions are represented with finite matrices and

Resonant Scattering of Gravitational Waves with Electromagnetic Waves
Chinese Physics Letters, 2023 A certain class of exact solutions of Einstein Maxwell spacetime in general relativity is discussed to demonstrate that at the level of theory, when certain parametric resonance condition is met, the interaction of electromagnetic field with a gravitational wave will display certain Lyapunov instability and lead to exponential amplification of a ...
