Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations
(Elsevier, 2017)
We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...
The evolution of internal waves in a rotating, stratified, circular basin and the influence of weakly nonlinear and nonhydrostatic accelerations
(AMER SOC LIMNOLOGY OCEANOGRAPHY, 2008-11)
The evolution of internal waves in a two-layer rotating circular lake was studied under nonlinear and weak nonhydrostatic effects. Inclusion of nonlinear acceleration allowed the waves to steepen at the rear of the crest ...
The Many-Object pilot wave theory.
(2013-08-12)
The "pilot wave." supplementary variables version of quantum mechanics diacusaed. It is claimed that in the many-object a semi-class picture of particles "guided" in their motion by waves m 3-spaces is difficult to ...
Electrostatic instabilities induced by large-amplitude left-hand polarized waves
(Blackwell Publishing Ltd, 2004)
We study the effect of a large-amplitude left-hand polarized wave on ion acoustic instabilities. We show that the presence of a finite amplitude left-hand polarized wave produces electrostatic instabilities above a threshold ...
Stabilization of right-hand polarized beam plasma instabilities due to a large-amplitude left-hand polarized wave: A simulation study
(Blackwell Publishing Ltd, 2004)
It has been recently shown that the presence of large amplitude left-hand polarized waves can change the linear properties of ion-beam plasma electromagnetic instabilities [Gomberoff, 2003]. Thus, it was shown that in the ...
Surface waves propagating on a turbulent flow
(AMER INST PHYSICS, 2016)
We study the propagation of monochromatic surface waves on a turbulent flow of liquid metal, when
the waves are much less energetic than the background flow. Electromagnetic forcing drives quasitwo-
dimensional turbulence ...
Spin wave vortex from the scattering on Bloch point solitons
(Elsevier, 2015)
The interaction of a spin wave with a stationary Bloch point is studied. The topological non-trivial structure of the Bloch point manifests in the propagation of spin waves endowing them with a gauge potential that resembles ...
Nonlinear ion-acoustic waves supported by an ion beam
(2007)
It is shown that in a plasma composed by electrons, a proton core, and a proton beam propagating along an external magnetic field, finite amplitude left-hand polarized waves propagating backward relative to the beam direction ...
Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
Dynamic and kinematic characterization of the impulsive wavemaker system in a numerical wave tank
(Amer Inst. Physics, 2020)
We study the dynamical response of a piston-type wavemaker in a numerical wave tank. The two-dimensional, fully viscous unsteady Navier-Stokes equations are solved on a two-phase flow configuration using the volume of fluid ...
