Superfluid turbulence from quantum Kelvin wave to classical Kolmogorov cascades.

The main topological feature of a superfluid is a quantum vortex with an identifiable inner and outer radius. A novel unitary quantum lattice gas algorithm is used to simulate quantum turbulence of a Bose-Einstein condensate superfluid described by the Gross-Pitaevskii equation on grids up to 5760(3). For the first time, an accurate power-law scaling for the quantum Kelvin wave cascade is deter...

Lévy-Kolmogorov scaling of turbulence

The Kolmogorov scaling law of turbulences has been considered the most important theoretical breakthrough in the last century. It is an essential approach to analyze turbulence data present in meteorological, physical, chemical, biological and mechanical phenomena. One of its very fundamental assumptions is that turbulence is a stochastic Gaussian process in small scales. However, experiment da...

Calculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics

In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

Non-Kolmogorov cascade of helicity-driven turbulence.

We solve the Navier-Stokes equations with two simultaneous forcings. One forcing is applied at a given large scale and it injects energy. The other forcing is applied at all scales belonging to the inertial range and it injects helicity. In this way we can vary the degree of turbulence helicity from nonhelical to maximally helical. We find that increasing the rate of helicity injection does not...

Kolmogorov and nonstationary spectra of optical turbulence.

Optical turbulence, which develops in the transverse directions when a laser beam propagates through a medium, is considered in the framework of the two-dimensional Schrodinger equation with a weak cubic nonlinearity. This classical model of optical turbulence was studied by many authors, but stationary (Kolmogorov) spectra that transfer transverse energy of the waves from large spatial scales...
