摘要：

A new type of dynamic matrix product ansatz is proposed. The states which satisfy the ''imaginary time'' Schrodinger equation are represented in the form of products of time-dependent and time-independent matrices. From the algebra among the matrices, the Bethe ansatz equation is derived for the asymmetric exclusion process and the XXZ spin chain under the periodic boundary condition.
