| Research Abstract |
A theory for the Leggett mode in Josephson junctions made of multi-gap superconductors has been constructed. The effect originating from the resonance between the Legget mode and the Josephson oscillations has been clarified in intrinsic Josephson junction stacks on the basis of this theory.
