Cluster mean-field study of the parity-conserving phase transition.

چکیده
The phase transition of the branching and annihilating random walk with even offspring is studied by N-cluster mean-field approximations on one-dimensional lattices. By allowing the system to reach zero branching rate a phase transition can be seen for any N < or = 12. Coherent anomaly extrapolations applied for the series of approximations results in nu(perpendicular) = 1.85(3) and beta=0.96(2).

Crossovers from parity conserving to directed percolation universality.
The crossover behavior of various models exhibiting phase transition to absorbing phase with parity conserving class has been investigated by numerical simulations and cluster mean-field method. In case of models exhibiting Z_2 symmetric absorbing phases (the cellular automaton version of the nonequilibrium kinetic Ising model (NEKIMCA) and a stochastic cellular automaton invented by Grassberge...
متن کاملMean-field solution of the parity-conserving kinetic phase transition in one dimension
A two-offspring branching annihilating random walk model, with finite reaction rates, is studied in one-dimension. The model exhibits a transition from an active to an absorbing phase, expected to belong to theDP2 universality class embracing systems that possess two symmetric absorbing states, which in onedimensional systems, is in many cases equivalent to parity conservation. The phase transi...
متن کاملRandom Phase Approximation For Allowed and Parity Non-conserving Electric Dipole Transition Amplitudes and its Connection with Many- Body Perturbation Theory and Coupled-Cluster Theory
The connections between the Random Phase Approximation (RPA) and Many-Body Perturbation Theory (MBPT) and its all order generalisation, the CoupledCluster Theory (CCT) have been explored. Explicit expressions have been derived for the electric dipole amplitudes for allowed and forbidden transitions induced by the parity non-conserving neutral weak interaction. The Goldstone diagrams associated ...
متن کاملPhase transition classes in triplet and quadruplet reaction-diffusion models.
Phase transitions of reaction-diffusion systems with site occupation restriction and with particle creation that requires n=3,4 parents, whereas explicit diffusion of single particles (A) is present are investigated in low dimensions by the mean-field approximation and simulations. The mean-field approximation of general nA-->(n+k)A, mA-->(m-l)A type of lattice models is solved and a different ...
متن کاملScale Invariance and Dynamic Phase Transitions in Diffusion-Limited Reactions
Many systems that can be described in terms of diffusion-limited ‘chemical’ reactions display non-equilibrium continuous transitions separating active from inactive, absorbing states, where stochastic fluctuations cease entirely. Their critical properties can be analyzed via a path-integral representation of the corresponding classical master equation, and the dynamical renormalization group. A...
