Transport coefficients of a gluon plasma.

Transport coefficients of gluon plasma are calculated for an SU(3) pure gauge model by lattice QCD simulations on 16(3) x 8 and 24(3) x 8 lattices. Simulations are carried out at slightly above the deconfinement transition temperature T(c), where a new state of matter is currently being pursued in BNL RHIC experiments. Our results show that the ratio of the shear viscosity to the entropy is less than one and the bulk viscosity is consistent with zero in the region 1.

Quiescent string dominance parameter F and classification of one-dimensional cellular automata.

The classification of rules may be one of the most fundamental targets in the study of cellular automata. In this paper, we propose a method for achieving such a classification, in which a new quiescent string dominance parameter F, which is orthogonal to lambda, is introduced. For N -neighbor and K -state cellular automata, in the region 1/K View Article and Find Full Text PDF
