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.

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

Journal Article 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

Journal Article 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

Journal Article 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.

Optical vortex interaction and generation via nonlinear wave mixing

Journal Article Lenzini, F. ; Dipartimento di Fisica, Universita di Firenze, via Sansone 1, IT-50019 Sesto Fiorentino ; Residori, S. ; ... - Physical Review. A

Optical vortex beams are made to interact via degenerate two-wave mixing in a Kerr-like nonlinear medium. Vortex mixing is shown to occur inside the medium, leading to exchange of topological charge and cascaded generation of vortex beams. A mean-field model is developed and is shown to account for the selection rules of the topological charges observed after the wave-mixing process. Fractional charges are demonstrated to follow the same rules as for integer charges.

Molecular beam epitaxy of thermodynamically metastable GaInAsSb alloys for medium IR-range photodetectors

Journal Article Semenov, A. N., E-mail: semenov@beam.ioffe.ru ; Terent'ev, Ya. V. ; Meltser, B. Ya. ; ... - Semiconductors

The features of growth of GaInAsSb alloy with In content as high as 25 mol % lattice-matched to GaSb by molecular beam epitaxy are studied. These alloys are promising for use as the active region of photodetector structures of the mid-infrared range. The results of the study of these alloys by double-crystal X-ray diffractometry, scanning electron microscopy, and photoluminescence are presented. It is shown that the Ga{sub x}In{sub 1-x}As{sub y}Sb{sub 1-y} alloys with x < 0.8 grown at 500 deg. C show the degradation of structural and optical properties as the layer thickness is increased.
