Dimensional Analysis and Weak Turbulence
In the study of weakly turbulent wave systems possessing incomplete self-similarity it is possible to use dimensional arguments to derive the scaling exponents of the Kolmogorov-Zakharov spectra, provided the order of the resonant wave interactions responsible for nonlinear energy transfer is known. Furthermore one can easily derive conditions for the breakdown of the weak turbulence approximat...

متن کاملImbalanced Weak MHD Turbulence
MHD turbulence consists of waves that propagate along magnetic fieldlines, in both directions. When two oppositely directed waves collide, they distort each other, without changing their respective energies. In weak MHD turbulence, a given wave suffers many collisions before cascading. “Imbalance” means that more energy is going in one direction than the other. In general, MHD turbulence is imb...
متن کاملImbalanced Weak Magnetohydrodynamic Turbulence
WeakMHD turbulence consists of waves that propagate along magnetic field lines, in both directions. When two oppositely directed waves collide, they distort each other, without changing their respective energies. Each wave suffers many collisions before cascading; by contrast, in strong MHD turbulence, waves cascade on the same timescale at which they collide. ‘‘ Imbalance ’’ means that more en...
متن کاملQuantum Weak Turbulence
The study of the phenomenon of quantum weak turbulence is extended by determining the quasiparticle spectrum associated with such a system using a Green’s function approach. The quasiparticle spectrum calculated establishes the dissipative regime and the inertial regime, hence a Kolmogorov type of picture. PACS number(s): 47.27.Ak, 67.40.Db, 67.40.Vs, 03.40.Gc
