Fluctuations in finite critical and turbulent systems
arXiv:cond-mat/0008243 · doi:10.1103/PhysRevLett.86.1007
Abstract
We show that hyperscaling and finite-size scaling imply that the probability distribution of the order parameter in finite size critical systems exhibit data collapse. We consider the examples of equilibrium critical systems, and a statistical model of ecology. We explain recent observations that the probability distribution of turbulent power fluctuations in closed flows is the same as that of the harmonic 2DXY model.
