One-dimensional model of freely decaying two-dimensional turbulence
Leonardo Campanelli
We construct a discrete shell-model for two-dimensional turbulence that takes into account local and nonlocal interactions between velocity modes in Fourier space. In real space, i…
Can the Blackett conjecture directly account for the magnetic fields of celestial bodies and galaxies? And, is a lab-based test for the Blackett conjecture feasible?
L. Campanelli
According to the Blackett conjecture, any neutral rotating body acquires a magnetic moment proportional to its angular momentum. Using the data on the dipolar magnetic field of Mar…
Creation of Universes from the Third-Quantized Vacuum
Leonardo Campanelli
We calculate the average numbers of closed, flat, and open universes spontaneously created from nothing in third quantization. The creation of universes is exponentially suppressed…
Dimensional analysis of two-dimensional turbulence
Leonardo Campanelli
We study the scaling properties of two-dimensional turbulence using dimensional analysis. In particular, we consider the energy spectrum both at large and small scales and in the "…
Smooth magnetogenesis
L. Campanelli, A. Marrone
In the Ratra scenario of inflationary magnetogenesis, the kinematic coupling between the photon and the inflaton undergoes a nonanalytical jump at the end of inflation. Using smoot…
Superhorizon magnetic fields
Leonardo Campanelli
[Abridged] We analyze the evolution of superhorizon-scale magnetic fields from the end of inflation till today. Whatever is the mechanism responsible for their generation during in…
