Journal ArticleDOI
Collective versus hub activation of epidemic phases on networks
TL;DR: A waning immunity, irrespective of its strength, leads to collective activation with finite threshold in scale-free networks with large degree exponent, at odds with canonical theoretical approaches.
Journal ArticleDOI
Sampling methods for the quasistationary regime of epidemic processes on regular and complex networks
TL;DR: This work compares different quasistationary simulation methods where the absorbing states are suitably handled and the thermodynamical limit of the original dynamics can be achieved and verifies the equivalence between RBC method and a weak external field for epidemics on networks.
Journal ArticleDOI
Phase transitions with infinitely many absorbing states in complex networks
TL;DR: It is conjecture that the critical behavior of the contact process in a HMF theory is a universal feature of absorbing-state phase transitions in complex networks, depending only on the locality of the interactions and independent of the number of absorbing states.

Absorbing state phase transitions with infinitely many absorbing states in complex networks
TL;DR: In this article, the authors investigate the properties of the threshold contact process (TCP), a process showing an absorbing-state phase transition with infinitely many absorbing states, on random complex networks.
Journal ArticleDOI
Quasi-stationary simulations of the directed percolation universality class in d = 3 dimensions
TL;DR: In this article, quasi-stationary simulations of three-dimensional models with a single absorbing configuration were presented, namely the contact process (CP), the susceptible-infected-susceptible (SIS) model and the contact replication process (CRP).
