Eddy diffusivities in scalar transport
L. Biferale, A. Crisanti, M. Vergassola +1
Standard and anomalous transport in incompressible flow is investigated using multiscale techniques. Eddy-diffusivities emerge from the multiscale analysis through the solution of…
Sporadicity and synchronization in one-dimensional asymmetrically coupled maps
F Cecconi, A Crisanti, M Falcioni A Vulpiani
A one-dimensional chain of sporadic maps with asymmetric nearest neighbour couplings is numerically studied. It is shown that in the region of strong asymmetry the system becomes s…
Critical behavior of nonequilibrium q-state systems
Andrea Crisanti, Peter Grassberger
We present two classes of nonequilibrium models with critical behavior. Each model is characterized by an integer , and is defined on configurations of -valued spins on reg…
On the TAP approach to the spherical p-spin SG model
A. Crisanti, H. -J. Sommers
In this letter we analyze the TAP approach to the spherical -spin spin glass model in zero external field. The TAP free energy is derived by summing up all the relevant diagrams…
Effective Action Method for Langevin Equation
A. Crisanti, U. Marini Bettolo Marconi
In this paper we present a formulation of the nonlinear stochastic differential equation which allows for systematic approximations. The method is not restricted to the asymptotic,…
Random bond Ising chain in a transverse magnetic field: A finite-size scaling analysis
A. Crisanti, H. Rieger
We investigate the zero-temperature quantum phase transition of the random bond Ising chain in a transverse magnetic field. Its critical properties are identical to those of the Mc…
