| Outline of Final Research Achievements |
We have performed fundamental studies for realizing nano-scale resonators which induce quantum vibrational modes. We have considered a simple model describing the nano-scale resonator and have calculated the transport properties using the Keldysh Green function methods. We have found that the number and states of the vibrational mode are controlled by the dc and ac, and gate voltage. We have also studied a molecule attached to a topological superconductor, which are expected to induce the quantum vibrational mode. We have revealed the anomalous features of conductance emerged at the zero bias voltage.
