Outline of Final Research Achievements

We studied spectral structure of some mathematical models of superlattice semiconductor devices. We studied the relation between the ratio of in-coming and out-going waves and the energy level E for perfect transmission, and found a kind of singularity. We also found that the relation between E and the phase factor, which is mentioned by RT effect, is broken. In another aspect, we introduced and studied the pseudo manifold of potentials for sustainability of resonances or embedded eigenvalues of discrete Schroedinger operator. In addition, we constructed quantum walks on simplicial complex as an application.
