Query: Thermodynamics of histories for the one-dimensional contact process   The dynamical activity K(t) of a stochastic process is the number of times it
changes configuration up to time t. It was recently argued that (spin) glasses
are at a first order dynamical transition where histories of low and high
activity coexist. We study this transition in the one-dimensional contact
process by weighting its histories by exp(sK(t)). We determine the phase
diagram and the critical exponents of this model using a recently developed
approach to the thermodynamics of histories that is based on the density matrix
renormalisation group. We find that for every value of the infection rate,
there is a phase transition at a critical value of s. Near the absorbing state
phase transition of the contact process, the generating function of the
activity shows a scaling behavior similar to that of the free energy in an
equilibrium system near criticality.
