Density waves and 1/f density fluctuations in granular flow.
We simulate the granular flow in a narrow pipe with a lattice–gas automaton model. We find that the density in the system is characterized by two features. One is that spontaneous density waves propagate through the system with well–defined shapes and velocities. The other is that density waves are so distributed to make the power spectra of density fluctuations as 1/fα noise. Three important p...
متن کاملDevelopment of KSTAR ECE imaging system for measurement of temperature fluctuations and edge density fluctuations.
The ECE imaging (ECEI) diagnostic tested on the TEXTOR tokamak revealed the sawtooth reconnection physics in unprecedented detail, including the first observation of high-field-side crash and collective heat transport [H. K. Park, N. C. Luhmann, Jr., A. J. H. Donné et al., Phys. Rev. Lett. 96, 195003 (2006)]. An improved ECEI system capable of visualizing both high- and low-field sides simultan...
متن کاملImpurity scattering and frequency dependent conductivity in spin density waves
– The quasiparticle contribution to the frequency dependent electric conductivity in the presence of randomly distributed impurities is calculated within mean field theory for spin density waves as formed in quasi one dimensional conductors like Bechgaard salts. Interchain hopping is taken into account and the effects of imperfect nesting are considered. In case of an electric field perpendicul...
متن کاملProperties of photon density waves in multiple-scattering media.
Amplitude-modulated light launched into multiple-scattering media, e.g., tissue, results in the propagation of density waves of diffuse photons. Photon density wave characteristics in turn depend on modulation frequency (omega) and media optical properties. The damped spherical wave solutions to the homogeneous form of the diffusion equation suggest two distinct regimes of behavior: (1) a high-...
متن کاملSubharmonic resonant excitation of edge waves by breaking surface waves
We have added a new Figure 3, where we show two frequency spectra. The first spectrum (Figure 3 a) is in absence of the breaking waves, where the first peak indicates the edge wave frequency and the second peak indicates the surface elevation frequency. The second frequency spectrum (Figure 3 b) is plotted in presence of breaking wave and indicates the suppression of the peak for the edge wave ...
