Toeplitz Matrices Within Dvr Formulation - Application to Quantum Scattering Problems
It is shown that the matrix obtained from the infinite order discrete variable representation (DVR) of a scattering problem has the structure of a Toeplitz matrix. The resulting properties can be used to reduce the associated infinite system of algebraic equations to a finite (and relatively small) one. An example is worked out to show the efficiency of the combined Toeplitz DVR approach.
