Abstract

A numerical analysis is presented of two-dimensional interaction between a transverse vortex and a composite compression wave that can exist in a thermodynamically nonideal medium. It is shown that the interaction of a composite wave involving a 'neutrally stable' shock with a vortex generates weakly damped outgoing acoustic waves; i.e., the shock is a source of sound. This phenomenon increases the post-shock acoustic noise level in an initially turbulent flow.

Interaction between a weak scanned light wave and high-power pumping in a medium having cubic nonlinearity

Afans'ev, A.A. ; Vlasov, R.A. - J. Appl. Spectrosc. (Engl. Transl.); (United States)

The authors propose a new method of mismatching for a holographic grating produced by periodic weak-wave angular scanning. The formation of the grating itself is qualitatively altered and the amplification is accompanied by weak-radiation spectrum distortion. The amplification in a transparent medium is of threshold-free type, it is sensitive to the parameters of the medium and the radiation, and it can be substantial even for a comparatively small ratio of the relaxation time to the scanning period. The method appears to be of interest in the production of amplification for weak beams and in measuring the parameters of nonlinear media.

On the calculation of equilibrium thermodynamic properties and the establishment of statistical-thermodynamically-consistent finite bound-state partition functions in nonideal multicomponent plasma mixtures within the chemical model

Zaghloul, Mofreh R. - Physics of Plasmas

The problem of the calculation of equilibrium thermodynamic properties and the establishment of statistical-thermodynamically consistent finite bound-state partition functions in nonideal multicomponent plasma systems is revised within the chemical picture. The present exploration accompanied by the introduction of a generalized consistent formulation, in terms of the solution of the inverse problem, clears ambiguities and gives a better understanding of the problem on top of pointing out weaknesses and inaccuracies/inconsistencies buried in widely used models in literature.

Determination of Pair Interaction Forces between Particles in Nonideal Dissipative Systems

Vaulina, O. S. ; Lisin, E. A. ; Gavrikov, A. V. ; ... - Physical Review Letters

A new technique for analyzing the pair interaction forces between particles in nonideal dissipative systems is presented. The technique is based on a solution of the inverse problem describing the movement of dust particles by a system of Langevin equations. Numerical simulations in a wide range of the parameters typical for dusty plasma experiments were performed to verify the solutions of the inverse problem. The first approbations of the proposed technique for analysis of intergrain interactions in a plasma of rf discharge are presented.

Low-amplitude magnetic vortex core reversal by non-linear interaction between azimuthal spin waves and the vortex gyromode

Sproll, Markus ; Noske, Matthias ; Kammerer, Matthias ; ... - Applied Physics Letters

We show, by experiments and micromagnetic simulations in vortex structures, that an active “dual frequency” excitation of both the sub-GHz vortex gyromode and multi-GHz spin waves considerably changes the frequency response of spin wave mediated vortex core reversal. Besides additional minima in the switching threshold, a significant broadband reduction of the switching amplitudes is observed, which can be explained by non-linear interaction between the vortex gyromode and the spin waves. We conclude that the well known frequency spectra of azimuthal spin waves in vortex structures are altered substantially, when the vortex gyromode is actively excited simultaneously.
