Real-space manifestations of bottlenecks in turbulence spectra.
An energy-spectrum bottleneck, a bump in the turbulence spectrum between the inertial and dissipation ranges, is shown to occur in the nonturbulent, one-dimensional, hyperviscous Burgers equation and found to be the Fourier-space signature of oscillations in the real-space velocity, which are explained by boundary-layer-expansion techniques. Pseudospectral simulations are used to show that such...
متن کاملHyperviscosity, Galerkin truncation, and bottlenecks in turbulence.
It is shown that the use of a high power alpha of the Laplacian in the dissipative term of hydrodynamical equations leads asymptotically to truncated inviscid conservative dynamics with a finite range of spatial Fourier modes. Those at large wave numbers thermalize, whereas modes at small wave numbers obey ordinary viscous dynamics [C. Cichowlas et al., Phys. Rev. Lett. 95, 264502 (2005)10.1103...
متن کاملNonlinear Cosmological Power Spectra in Real and Redshift–Space
We present an expression for the nonlinear evolution of the cosmological power spectrum based on following Lagrangian trajectories. This is simplified using the Zel’dovich approximation to trace particle displacements, assuming Gaussian initial conditions. The model is found to exhibit the transfer of power from large to small scales expected in self-gravitating fields. Some exact solutions are...
متن کاملCollapse spectra of cloud turbulence
The collapse spectra of cloud turbulence are obtained from the governing equations of the self-gravitating system. The spectra can be used to explain the observed scaling behaviour of the internal velocity dispersions and macrostructural density inhomogeneity in molecular clouds.
متن کاملPhase Space Bottlenecks in Enzymatic Reactions
The definition of a transition state on an individual reactive trajectory is made via a committor analysis. In the past, the bottleneck definition has often been applied in configuration space. This is an approximation, and in order to expand this definition, we are revisiting an enzyme in which we had identified a fast subpicosecond motion that makes the reaction possible. First we used a time...
