Wave scattering by discrete breathers [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2003
We present a theoretical study of linear wave scattering in one-dimensional nonlinear lattices by intrinsic spatially localized dynamic excitations or discrete breathers. These states appear in various nonlinear systems and present a time-periodic localized scattering potential for plane waves.

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 ...

Rydberg optical Feshbach resonances in cold gases [PDF]

open access: yes, 2017
We propose a novel scheme to efficiently tune the scattering length of two colliding ground-state atoms by off-resonantly coupling the scattering-state to an excited Rydberg-molecular state using laser light. For the s-wave scattering of two colliding ${^

Smoothed Corners and Scattered Waves [PDF]

open access: yesSIAM Journal on Scientific Computing, 2016
We introduce an arbitrary order, computationally efficient method to smooth corners on curves in the plane, as well as edges and vertices on surfaces in $\mathbb R^3$. The method is local, only modifying the original surface in a neighborhood of the geometric singularity, and preserves desirable features like convexity and symmetry.

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

Theory of Raman Scattering from Orbital Excitations in Manganese Oxides [PDF]

open access: yes, 2001
We present a theory of the Raman scattering from the orbital wave excitations in manganese oxides. Two excitation processes of the Raman scattering are proposed.

Back to Bohr: Quantum Jumps in Schrödinger’s Wave Mechanics

open access: yesQuantum Reports
The measurement problem of quantum mechanics concerns the question as to under which circumstances coherent wave evolution becomes disrupted to produce eigenstates of observables, instead of evolving superpositions of eigenstates.

Ocean waves across the Arctic: Attenuation due to dissipation dominates over scattering for periods longer than 19 s

open access: yesGeophysical Research Letters, 2016
The poorly understood attenuation of surface waves in sea ice is generally attributed to the combination of scattering and dissipation. Scattering and dissipation have very different effects on the directional and temporal distribution of wave energy ...

Ballistic phonon lensing by the non-planar interfaces of embedded nanoparticles

open access: yesNew Journal of Physics, 2023
In this work, we investigate the scattering behavior of a ballistic phonon wave incident on a dopant spherical nanoparticle embedded within a pure crystal through molecular dynamics simulations.

A Procedure to Calculate First-Order Wave-Structure Interaction Loads in Wave Farms and Other Multi-Body Structures Subjected to Inhomogeneous Waves

open access: yesEnergies, 2021
A typical assumption when performing analytical, numerical, and experimental studies in wave–structure interaction in multi-body problems such as for wave farms and very large floating structures is the homogeneity of the wave field.
