We consider a homogeneous continuous-time random walk (CTRW) on the lattice $Z^{d}$, $d=1,2,ldots$ which is a kind of random trap model in a time-dependent (``dynamic'') environment. The waiting time distribution is renewed at each jump, and is given

We perform computer simulations of some one-dimensional models of coupled map lattices (CML) with symmetry and diffusive nearest neighbour coupling, to study Ising-type transitions. Such transitions appear to be related to the presence of a dip (mini

We study the asymptotic behavior of correlations for a general “two-particle” operator $${{\mathcal T}}$$ acting on the Hilbert space $${\ell_2({\mathbb Z}^d\times {\mathbb Z}^d)}$$ , for all dimension d = 1, 2, . . .. $${{\mathcal T}}$$ is writt

We consider a discrete-time random walk on Z d , d = 1;2;::: in a random environment with Markov evolution in time. We complete and extend to all dimension d ‚ 1 the results obtained in [2] on the time decay of the correlations of the \environment

We present a (mostly) rigorous approach to unbounded and bounded (open) dilute random Lorentz gases. Relying on previous rigorous results on the dilute (Boltzmann–Grad) limit we compute the asymptotics of the Lyapunov exponent in the unbounded case

We consider a one-dimensional lattice of expanding antisymmetric maps [−1, 1]→[−1, 1] with nearest neighbor diffusive coupling. For such systems it is known that if the coupling parameter e is small there is unique stationary (in time) state, w

We study a one-dimensional semi-infinite system of identical particles with random lifetimes, interacting with a charged particle (the leftmost) which is driven by a constant positive force~F. Particles interact through elastic collisions and at the
