| Outline of Final Research Achievements |
The diamagnetism is a essential property of all superconductors. However, the paramagnetic response has been observed in a number of small superconductors. The mechanism and basic physical picture of the paramagnetic response has been an open question. In this project, we make clear (1) odd-frequency Cooper pairs appear at a surface of a topological superconductor, (2) odd-frequency Cooper pairs are paramagnetic, (3) therefore odd-frequency Cooper pairs are responsible for the paramagnetic response of a small topological superconductor at low temperature.
