Adaptive Density-Matrix Renormalization-Group study of the disordered antiferromagnetic spin-1/2 Heisenberg chain
Alexander H. O. Wada, José A. Hoyos
Using the recently introduced adaptive density-matrix renormalization-group method, we study the many spin-spin correlations of the spin- antiferromagnetic Heisenberg chain wi…
Critical properties of the Susceptible-Exposed-Infected model with correlated temporal disorder
Alexander H. O. Wada, José A. Hoyos
In this paper we study the critical properties of the non-equilibrium phase transition of the Susceptible-Exposed-Infected model under the effects of long-range correlated time-var…
Extinction transitions in correlated external noise
Alexander H. O. Wada, Matthew Small, Thomas Vojta
We analyze the influence of long-range correlated (colored) external noise on extinction phase transitions in growth and spreading processes. Uncorrelated environmental noise (i.e.…
Fractional Brownian motion with a reflecting wall
Alexander H. O. Wada, Thomas Vojta
Fractional Brownian motion, a stochastic process with long-time correlations between its increments, is a prototypical model for anomalous diffusion. We analyze fractional Brownian…
Critical properties of the contact process with quenched dilution
Alexander H. O. Wada, Mário J. de Oliveira
We have studied the critical properties of the contact process on a square lattice with quenched site dilution by Monte Carlo simulations. This was achieved by generating in advanc…
Critical properties of the susceptible-exposed-infected model on a square lattice
Alexander H. O. Wada, Tânia Tomé, Mário J. de Oliveira
The critical properties of the stochastic susceptible-exposed-infected model on a square lattice is studied by numerical simulations and by the use of scaling relations. In the pre…
