Finite-dimensional representation of the quadratic algebra of a generalized coagulation-decoagulation model. J.
Random walk of second class particles in product shock measures
In the ﬁrst case we have only coagulation, in the second case we have coagulation and decoagulation.
Reaction-Diffusion Processes, Critical Dynamics and Quantum Chains
We now consider the case when the coagulation and the decoagulation processes coexist and we have all terms in Eq. (4.29).
Reaction-Diffusion Processes, Critical Dynamics and Quantum Chains
This can now be studied by performing perturbative calculations in the limit of a small decoagulation rate.
Reaction-Diffusion Processes, Critical Dynamics and Quantum Chains
Although the Hamiltonian describing the coagulation and decoagulation processes is not known to be integrable it was shown in that the gap-probability function for this model can be computed exactly and this is an indication that the model is integrable.
Reaction-Diffusion Processes, Critical Dynamics and Quantum Chains
It can always be brought to a hermitian form through a similarity transformation if one out of the three possible forward-backward reactions (annihilation-creation, death-birth, coagulation-decoagulation) take place.
