Title: Dynamics of complex systems: 1/f fluctuations, Self-organised Criticality and Absorbing Phase Transitions in a Deterministic Lattice Gas
Abstract:We show that some new results on the power spectrum of the density fluctuations of the Deterministic Lattice Gas can be reduced to the critical properties of the gas at the absorbing phase transition at low densities. We also show that the Deterministic Lattice Gas is in the Manna universality class of absorbing phase transitions, despite the deterministic nature of its dynamics. We discuss how the exponent beta of the power spectrum S(f)\proto 1/f^\beta depends on system size and discuss its relation to effective Langevin equations.
