Dynamics of Jackson networks: perturbation theory
Reuven Zeitak
We introduce a new formalism for dealing with networks of queues. The formalism is based on the Doi-Peliti second quantization method for reaction diffusion systems. As a demonstra…
Lyapounov exponent and density of states of a one-dimensional non-Hermitian Schroedinger equation
Bernard Derrida, Jesper Lykke Jacobsen, Reuven Zeitak
We calculate, using numerical methods, the Lyapounov exponent gamma(E) and the density of states rho(E) at energy E of a one-dimensional non-Hermitian Schroedinger equation with of…
Anomalous scaling in passive scalar advection: Monte-Carlo Lagrangian trajectories
Omri Gat, Itamar Procaccia, Reuven Zeitak
We present a numerical method which is used to calculate anomalous scaling exponents of structure functions in the Kraichnan passive scalar advection model (R. H. Kraichnan, Phys.…
Multiscaling in passive scalar advection as stochastic shape dynamics
Omri Gat, Reuven Zeitak
The Kraichnan rapid advection model is recast as the stochastic dynamics of tracer trajectories. This framework replaces the random fields with a small set of stochastic ordinary d…
Distribution of domain sizes in the zero temperature Glauber dynamics of the 1 D Potts model
Bernard Derrida, Reuven Zeitak
For the zero temperature Glauber dynamics of the -state Potts model, we calculate the exact distribution of domain sizes by mapping the problem on an exactly soluble one-species…
Persistent spins in the linear diffusion approximation of phase ordering and zeros of stationary gaussian processes
Bernard Derrida, Vincent Hakim, Reuven Zeitak
The fraction r(t) of spins which have never flipped up to time t is studied within a linear diffusion approximation to phase ordering. Numerical simulations show that, even in this…
