An entropy-based, scale-dependent centrality
L. R. Schwengber, S. D. Prado, S. R. Dahmen
In this article we introduce an entropy-based, scale-dependent centrality that is evaluated as the Shannon entropy of the distribution at time t of a continuous-time random walk. I…
Transfer matrix in counting problems made easy
Roberto da Silva, Silvio R. Dahmen, J. R. Drugowich de Felício
The transfer matrix is a powerful technique that can be applied to statistical mechanics systems as, for example, in the calculus of the entropy of the ice model. One interesting w…
Long-range epidemic spreading with immunization
Florian Linder, Johannes Tran-Gia, Silvio R. Dahmen +1
We study the phase transition between survival and extinction in an epidemic process with long-range interactions and immunization. This model can be viewed as the well-known gener…
Space Representation of Stochastic Processes with Delay
Silvio R. Dahmen, Haye Hinrichsen, Wolfgang Kinzel
We show that a time series evolving by a non-local update rule with two different delays can be mapped onto a local process in two dimension…
Stochastic differential equations with time-delayed feedback and multiplicative noise
Silvio R. Dahmen, Haye Hinrichsen
The stochastic differential equation with a time-delayed feedback and a multiplicative Gaussian noise is shown to be related to Kardar-…
Multicritical behavior of the diluted contact process
Silvio R. Dahmen, L. Sittler, H. Hinrichsen
We study a contact process on a two-dimensional square lattice which is diluted by randomly removing bonds with probability p. For p<1/2 and varying birth rate the model was sh…
