Introduction to the Directed Percolation Universality Class and the Contact Process

Statistical Physics and Complexity Group meeting

Introduction to the Directed Percolation Universality Class and the Contact Process

Event details

I will give an introduction to the directed percolation problem (first introduced by Hammersley and Broadbent in 1957) and the associated critical behaviour and scaling. I will also discuss a simple stochastic epidemic model that exhibits the same scaling and try to argue why the Directed Percolation universality class is important. If time permits I will discuss related processes that may or may not exhibit the same scaling.
