Abstract: I show a generalization of the Coordinate Bethe Ansatz for open ASEP (or XXZ) model that allows to deal with non-diagonal matrices. This Ansatz lead to some eigenvectors of the model, but does not provide a complete spectrum. To get the full spectrum, one needs another (new) Bethe Ansatz, called Matrix Coordinate Bethe Ansatz, that I will also present. It uses both technics of Coordinate and Matrix Bethe Ansaetzen.
Together, the Generalized and Matrix Coordinate Bethe Ansaetzen give the complete set of eigenvectors and eigenvalues of the model.
