Abstract
We show that an inhomogeneous coagulation/decoagulation model can be
mapped to a quadratic fermionic model via a Jordan-Wigner
transformation. The spectrum for this inhomogeneous model is computed
exactly and the spectral gap is described for some examples. We
construct our inhomogeneous model from two different homogeneous models
joined by one special bond (impurity). The homogeneous models we started
with are the coagulation/decoagulation models studied previously using
the Jordan-Wigner transformation.
