The one-dimensional reaction diffusion process AA→A and A∅A→AAA is exactly solvable through the empty interval method if the diffusion rate equals the coagulation rate. Independently of the particle production rate, the model is always in the universality class of diffusion-annihilation. This allows us to check analytically the universality of finite-size scaling in a non-equilibrium critical point.

Scale-invariant universal crossing probability in one-dimensional diffusion-limited coalescence
The crossing probability in the time direction is defined for an off-equilibrium reaction-diffusion system as the probability that the system of size L is still active at time t, in the finite-size

TLDR
A field-theoretical model describing simple one-species reaction-diffusion systems with an external source is analyzed from a renormalization-group point of view and it is shown that when the dimension of the system is larger than the upper critical dimension, the behavior is governed by a trivial fixed point dominated by diffusion.

TLDR
The steady-state phase diagram of the one-dimensional reaction-diffusion model 2A-->3A,2A-->0 is studied through the non-Hermitian density matrix renormalization group, where the value of beta/nu(perpendicular) is close to thevalue of the parity conserving universality class, in spite of the absence of local conservation laws.

TLDR
Numerical simulations and cluster mean-field approximations with coherent anomaly extrapolation show that the critical line of the 1d annihilation-fission process is separated into two regions, and the high diffusion region seems to be well described by the cyclically coupled directed percolation and annihilating random walk.

TLDR
The results suggest that the transition might belong to a different universality class that has not been investigated before, and this is surprising since the model does not have an explicit parity-conserving symmetry.

TLDR
Computer simulations in 1D yielded critical exponents consistent with directed percolation, for the first time placing a model with infinitely many absorbing states firmly in the directed-percolation universality class.
