Universality in the periodicity manifestations in the non-locally coupled map lattices in the turbulent regime

Tokuzo Shimada, Shou Tsukada

In the turbulent regime of coupled map lattice with non-local interaction the maps systematically form periodic cluster attractors and their remnants by synchronization due to the…

Periodic Cluster Attractors and their Stabilities in the Turbulent Globally Coupled Map Lattice

Tokuzo Shimada, Kengo Kikuchi

The Globally Coupled Map Lattice (GCML) is one of the basic model of the intelligence activity. We report that, in its so-called turbulent regime, periodic windows of the element m…

A Resolution of the Puzzle of the Posi-nega Switch Mechanism in the Globally Coupled Map Lattice

T. Shimada, S. Tsukada

We revisit the globally coupled map lattice (GCML). We use a family of universal 'curves of balance' between two conflicting tendencies in the model- the randomness in each map and…

Rapidity Gaps in Quark and Gluon Jets - a Perturbative Approach

Wolfgang Ochs, Tokuzo Shimada

We derive the probability for rapidity gaps in a parton cascade and investigate the dual connection with hadronic final states. A good description of observations in e+e- annihilat…

Phenomenology of Globally Coupled Map Lattice and its Extension

Tokuzo Shimada

We revisit the globally coupled map lattice (GCML) and also propose a new extended globally coupled map lattice (EGCML) with an inverse power law interaction. In GCML we clarify th…

Rapidity Gaps in e+e- Annihilation and Parton Hadron Duality

W. Ochs, T. Shimada

We calculate the probability for rapidity gaps in the parton cascade for different approximations within the perturbative QCD and compare the results with recent measurements. The…
