Epidemic processes can be described as the spread and decay of an infectious disease. Depending on the balance between these two processes, the infection may either die out or spread over the entire population. The two regimes of survival and extinction are typically separated by acontinuous phase transition. Epidemic processes in which thesusceptibility to infection is independent of previous infections aredescribed by directed percolation (DP). In this talk I will introduce anepidemic model (DP) with immunization, i.e. with different probabilitiesfor the first infection and subsequent infections. I will discuss howimmunization modifies the critical behaviour of the epidemic model.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
