How winding is the coast of Britain ? Conformal invariance of rocky shorelines
G. Boffetta, A. Celani, D. Dezzani +1
We show that rocky shorelines with fractal dimension 4/3 are conformally invariant curves by measuring the statistics of their winding angles from global high-resolution data. Such…
Inverse turbulent cascades and conformally invariant curves
D. Bernard, G. Boffetta, A. Celani +1
We offer a new example of conformal invariance far from equilibrium -- the inverse cascade of Surface Quasi-Geostrophic (SQG) turbulence. We show that temperature isolines are stat…
Multi-particle dispersion in fully developed turbulence
L. Biferale, G. Boffetta, A. Celani +3
The statistical geometry of dispersing Lagrangian clusters of four particles (tetrahedra) is studied by means of high-resolution direct numerical simulations of three-dimensional h…
Lagrangian statistics of particle pairs in homogeneous isotropic turbulence
L. Biferale, G. Boffetta, A. Celani +3
We present a detailed investigation of the particle pair separation process in homogeneous isotropic turbulence. We use data from direct numerical simulations up to Taylor's Reynol…
Inverse cascade in two-dimensional turbulence: deviations from Gaussianity
G. Boffetta, A. Celani, M. Vergassola
High resolution numerical simulations of stationary inverse energy cascade in two-dimensional turbulence are presented. Deviations from Gaussianity of velocity differences statisti…
Dispersion of passive tracers in closed basins: beyond the diffusion coefficient
V. Artale, G. Boffetta, A. Celani +2
We investigate the spreading of passive tracers in closed basins. If the characteristic length scale of the Eulerian velocities is not very small compared with the size of the basi…
