It is argued that the universe may have experienced such a phase of superfluid-like turbulence due to the existence of a coherent state with non-topological charge and a network of global strings.

A network of vortices in a superfluid system exhibits turbulent behavior. It is argued that the universe may have experienced such a phase of superfluid-like turbulence due to the existence of a coherent state with non-topological charge and a network of global : Ben-Ami Gradwohl.

The primary application is to cosmology, but we also discuss the reduction to the non-relativistic nonlinear Schr\"{o}dinger equation, which is widely used in describing superfluidity and.

Its interest is however not limited to the turbulence context. It turns out that Burgers’ equation can also be used to describe completely different processes such as growth of interface, or even structure formation in the Universe.

It therefore bridges compressible turbulence and : B. Dubrulle. S.N. Fisher, G.R. Pickett, in Progress in Low Temperature Physics, 7 NONMECHANICAL GENERATION OF VORTICITY BY THE KIBBLE-ZUREK MECHANISM DURING A RAPID PHASE TRANSITION. Superfluid 3 He has many analogies with cosmology.

In particular, various predicted defects in space-time have direct analogies with known defects in the superfluid 3 He condensate. Principles of the theory of turbulence in relativistic cosmology are developed. By averaging Einstein's equations over stochastic fields a self-consistent system of equations is obtained which describes statistically: (1) the influence of the turbulence on the ‘basic state of the Universe (the background) on which the turbulence develops; (2) the behaviour of the turbulence on the Cited by: 4.

Turbulence is ubiquitous in astrophysics, ranging from cosmology, interstellar medium to stars, supernovae, accretion disks, etc. Large scales and small viscosities combine to form large Reynolds numbers.

Because it is not possible in a single article to review all the above scenarios, we limit ourselves to stars, in which thermal instabilities give rise to turbulent convection as the dominant Cited by:   A model employing such reconnections was able to account for turbulence in a superfluid [ 15 ].

(Right) These reconnections can create Kelvin waves in which a vortex line oscillates about an equilibrium position like a plucked string (the rightmost wavy vortex compared to the undisturbed filament to its left). This interesting book provides the physical and mathematical background for a theory describing the universe as a quantum superfluid, and how dark energy and dark matter arise.

Presenting a novel theory spanning many different fields in physics, the key concepts in each field are introduced. Abstract The universe may have undergone a superfluid-like phase during its evolution, resulting from the injection of nontopological charge into the spontaneously broken vacuum.

In the presence of vortices this charge Superfluid-like turbulence in cosmology book identified with angular momentum. This leads to turbulent domains on the scale of the correlation : Ben-Ami Gradwohl. This book is primarily concerned with turbulence in superfluid helium. Quantized vorticity has traditionally generated great interest among physicists but there are now also important engineering applications, such as liquid helium cooling of superconducting : Hardcover.

reverences. Certainly, the Euler equations are inviscid, and most cosmology books do not have the terms “viscosity, diffusivity, and turbulence” in their index or contents [1]. However, a different view is that the self-gravitational condensation of structures in the universe is limited primarily by viscous and.

Fluid Mechanics Explains Cosmology, Dark Matter, Dark Energy, and Life turbulence, the big bang is simply a Planck-Kerr instability similar to supernova pair production, but with sufficient temperature to extract mass-energy from the vacuum and produce the universe in an inflationary event.

Cosmology The Big Bang theory of the evolution of the observable universe assumes that space is isotropic.

It also assumes that space is homogeneous. These two assumptions together are known as the cosmological ofthe observations suggest that, on distance scales much larger than galaxies, galaxy clusters are "Great" features, but small compared to so-called multiverse.

The topic of chaos has become quite popular over the last few decades. A system is defined to be chaotic when its behavior is so sensitive to some factor that it is extremely difficult to predict. The field of chaos is the study of chaotic behavior.

A good example of chaotic behavior is the flow of a fluid with a Reynolds number between and Superfluid turbulence - No viscosity - Vortex lines have fixed circulation and infinitesimal core radius Rotation + axial flow = turbulence Note the growth of Kelvin waves and vortex reconnections Tsubota, Araki & Barenghi, Phys.
