| Research Abstract |
The main result in this study is that the electric state within the vortex core in high temperature superconductors is shown to be quite different from that in ordinary superconductors. Using a bolometric technique, we have improved the sensitivity of the microwave detection for two order of magnitude compared to the ordinary cavity technique. We showed that high temperature superconductor is placed in the new quantum regime, "superclean regime" which was impossible to access in ordinary superconductors.
