Solvable model for spatiotemporal chaos
The study of temporal chaos in low-dimensional systems, some of which can be described by low-dimensional maps @1,2#, was extremely beneficial for the understanding of turbulence. In 1984 coupled map lattices ~CMLs! were introduced into the physical literature as a tool for studying spatiotemporal chaos in spatially extended, i.e., highdimensional systems @3#. They consist of spatially coupled ...

We use some general results regarding positive maps to exhibit examples of non-decomposable maps and 2 ×2N , N ≥ 2, bound entangled states, e.g. non distillable bipartite states of N+N qubits.

An algorithm to characterize collective motion is presented, with the introduction of “collective Lyapunov exponent”, as the orbital instability at a macroscopic level. By applying the algorithm to a globally coupled map, existence of low-dimensional collective chaos is confirmed, where the scale of (high-dimensional) microscopic chaos is separated from the macroscopic motion, and the scale app...
متن کاملGENERAL SYNCHRONIZATION OF COUPLED PAIR OF CHAOTIC ONE-DIMENSIONAL GAUSSIAN MAPS
In this paper we review some recent ideas of synchronization theory. We apply this theory to study the different synchronization aspects of uni-directionally coupled pair of chaotic one-dimensional Gaussian maps.

We consider a 5-dimensional scalar-tensor theory which is a direct generalization of the original 4-dimensional Brans-Dicke theory to 5-dimensions. By assuming that there is a hypersurface-orthogonal spacelike Killing vector field in the underlying 5-dimensional spacetime, the theory is reduced to a 4-dimensional theory where the 4-metric is coupled with two scalar fields. The cosmological impl...
