Variability of Contact Process in Complex Networks
Variability of Contact Process Complex Networks Social and Information Networks
2012/4/19
We study numerically how the structures of distinct networks influence the epidemic dynamics in contact process. We first find that the variability difference between homogeneous and heterogeneous net...
Critical exponents of the pair contact process with diffusion
PCPD universality class critical systems
2012/2/27
We study the pair contact process with diffusion (PCPD) using Monte Carlo simulations, and concentrate on the decay of the particle density $\rho$ with time, near its critical point, which is assumed ...
The threshold-two contact process on a random r-regular graph has a first order phase transition
The threshold-two contact process r-regular graph phase transition
2010/11/12
We consider the discrete time threshold-two contact process on a random $r$-regular graph on $n$ vertices. In this process, a vertex with at least two occupied neighbors at time $t$ will be occupied ...

Contact process defect: universal oasis nonuniversal scaling

The extinction transition in the presence of a localized quenched defect is studied umerically.
When the bulk is at criticality, the correlation length diverges and even an infinite system cannot ”de...

On the critical behavior at the lower phase transition of the contact process
Contact process phase transition critical behavior interacting particle system oriented percolation

We present general results for the contact process by a method which applies to all transitive graphs of bounded degree, including graphs of exponential growth. The model infection rates are varied th...
