A Semi-Analytical Model for Studying Hydroelastic Behaviour of a Cylindrical Net Cage under Wave Action

open access: yesJournal of Marine Science and Engineering, 2021
In the present study, a semi-analytical model based on the small-amplitude wave theory is developed to describe the wave fields around a single gravity-type cylindrical open fish net cage.

Suppression of Quantum Scattering in Strongly Confined Systems [PDF]

open access: yes, 2006
We demonstrate that scattering of particles strongly interacting in three dimensions (3D) can be suppressed at low energies in a quasi-one-dimensional (1D) confinement.

A Quantum Scattering Interferometer [PDF]

open access: yes, 2007
The collision of two ultra-cold atoms results in a quantum-mechanical superposition of two outcomes: each atom continues without scattering and each atom scatters as a spherically outgoing wave with an s-wave phase shift.

The derivation of scaling relationship between acoustic and electromagnetic scattering by spheres

open access: yesAIP Advances, 2013
The rigorous theory of the conversion between the scattering of uniform plane electromagnetic wave by a perfectly conducting sphere and the scattering of uniform plane acoustic wave by a rigid sphere is studied in this paper.

Simulating Meson Scattering on Spin Quantum Simulators [PDF]

open access: yesQuantum
Studying 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 ...

Numerical Simulation and Backscattering Characteristics of Freak Waves Based on JONSWAP Spectrum

open access: yesFrontiers in Marine Science, 2022
Based on the linear wave superposition model, we realize the numerical simulation of three-dimensional (3-D) surface waves combined with JONSWAP spectrum and stereo wave observation project (SWOP) directional function.

Quantum Scattering Theory in a Discrete Representation

open access: yesEPJ 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

Scattering amplitude from Bethe-Salpeter wave function inside the interaction range [PDF]

open access: yes, 2018
We propose a method to calculate scattering amplitudes using the Bethe-Salpeter wave function inside the interaction range on the lattice. For an exploratory study of this method, we evaluate a scattering length of $I=2$ S-wave two pions by the use of ...
