  Abstract:
We study a one-dimensional branching-coalescing model on a chain of length L with reflecting boundaries. The phase transitions of this model is investigated in a canonical ensemble by using the Yang-Lee description of the non-equilibrium phase transitions. Numerical study of the canonical partition function zeros reveals two second-order phase transitions in the system. Both transition points are determined by the density of the particles on the chain. In some regions the density profile of the particles has a shock structure.
