Confinement-induced p-wave resonances from s-wave interactions

open access: yes, 2010
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-wave resonances in mixed dimensions. We develop two-body scattering theories in all three cases of 0D-3D, 1D-3D, and 2D-3D mixtures and determine the positions of

Shape-preserving and unidirectional frequency conversion using four-wave mixing Bragg scattering [PDF]

open access: yes, 2018
In this work, we investigate the properties of four-wave mixing Bragg scattering in a configuration that employs orthogonally polarized pumps in a birefringent waveguide. This configuration enables a large signal conversion bandwidth, and allows strongly

Quasiparticle Scattering Interference in (K,Tl)FexSe2 Superconductors

open access: yes, 2011
We model the quasiparticle interference (QPI) pattern in the recently discovered (K,Tl)Fe_xSe2 superconductors. We show in the superconducting state that, due to the absence of hole pockets at the Brillouin zone center, the quasiparticle scattering ...

Resonant Scattering of Gravitational Waves with Electromagnetic Waves

open access: yesChinese 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 ...

Collapse of wave functions in Schrödinger’s wave mechanics

open access: yesScientific Reports
We show that inelastic scattering in a short-range potential leads to a collapse of the wave function within standard evolution through the Schrödinger equation, whereas elastic scattering will not collapse the wave function.

Numerical simulation study of lower hybrid wave scattering full-wave solution in scrap-off layer

open access: yesHe jishu
BackgroundLower hybrid current drive (LHCD) is one of the main auxiliary heating and current driving methods for Tokamak, and studies have shown that the boundary parasitics effect of lower hybrid (LH) wave in scrap-off layer (SOL) significantly ...

A novel method for investigation of acoustic and elastic wave phenomena using numerical experiments

open access: yesTheoretical and Applied Mechanics Letters, 2020
The emergence of new types of composite materials, the depletion of existing hydrocarbon deposits, and the increase in the speed of trains require the development of new research methods based on wave scattering.

Time-Dependent Modelling of the Wave-Induced Vibration of Ice Shelves

open access: yesJournal of Marine Science and Engineering, 2023
This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused on the effect of changes in the draft on the vibration of the ice shelf and presents both time-domain and frequency-domain ...

Resonant Scattering of Ultracold Atoms in Low Dimensions

open access: yes, 2008
Low energy scattering amplitudes for two atoms in one- and two-dimensional atomic wave guides are derived for short range isotropic and resonant interactions in high partial wave channels.

Variational description of continuum states in terms of integral relations [PDF]

open access: yes, 2010
Two integral relations derived from the Kohn Variational Principle (KVP) are used for describing scattering states. In usual applications the KVP requires the explicit form of the asymptotic behavior of the scattering wave function.
