A family of discrete-time exactly-solvable reaction-diffusion processes on a one-dimensional lattice
نویسندگان
چکیده
A two-parameter family discrete-time exactly-solvable reaction-diffusion processes on a one-dimensional lattice is introduced, which contains the asymmetric simple exclusion process and the drop-push model as particular cases. The reaction is rewritten in terms of boundary conditions, and the conditional probabilities are calculated using the Bethe-ansatz. This is the discrete-time version of the continuous-time processes already investigated in [1–3]. The driftand diffusion-rates of the particles are also calculated for the two-particle sector. PACS numbers: 05.40.-a, 02.50.Ga

On the solvable multi–species reaction–diffusion processes
A family of one–dimensional multi–species reaction–diffusion processes on a lattice is introduced. It is shown that these processes are exactly solvable, provided a nonspectral matrix equation is satisfied. Some general remarks on the solutions to this equation, and some special solutions are given. The large–time behavior of the conditional probabilities of such systems are also investigated. ...
متن کاملAnnihilation–diffusion processes: an exactly solvable model
A family of diffusion–annihilation processes is introduced, which is exactly solvable. This family contains parameters that control the diffusionand annihilationrates. The solution is based on the Bethe ansatz and using special boundary conditions to represent the reaction. The processes are investigated, both on the lattice and on the continuum. Special cases of this family of processes are th...
متن کاملDiscontinuous Phase Transition in an Exactly Solvable One-Dimensional Creation-Annihilation System
An exactly solvable reaction-diffusion model consisting of first class particles in the presence of a single second class particle is introduced on a one-dimensional lattice with periodic boundary condition. The number of first class particles can be changed due to creation and annihilation reactions. It is shown that the system undergoes a discontinuous phase transition from a phase with no em...
متن کاملMulti-species extension of the solvable partially asymmetric reaction-diffusion processes
By considering the master equation of the partially asymmetric diffusion process on a one-dimensional lattice, the most general boundary condition (i.e. interactions) for the multi-species reaction-diffusion processes is considered. Resulting system has various interactions including diffusion to left and right, two-particle interactions AαAβ → AγAδ and the extended n-particle drop-push interac...
متن کاملExactly solvable models through the generalized empty interval method, for multi-species interactions
Multi-species reaction-diffusion systems, with nearest-neighbor interaction on a one-dimensional lattice are considered. Necessary and sufficient constraints on the interaction rates are obtained, that guarantee the closedness of the time evolution equation for E n(t)’s, the expectation value of the product of certain linear combination of the number operators on n consecutive sites at time t. ...
