| Outline of Final Research Achievements |
Symmetry and its spontaneous breaking is one of the important concepts in modern physics. In general, it is known that when a continuous symmetry is spontaneously broken, there appears the gapless excitation modes called the Nambu-Goldstone mode (Nambu-Goldstone of the theorem). The pions and spin waves in the ferromagnets are examples of NG modes. The original theorem was formulated in the relativistic systems. We generalize the Nambu-Goldstone theorem in the Lorentz invariant systems to that in the nonrelativistic systems, and we clarify the relationship of spontaneous symmetry breaking and Nambu-Goldstone mode that was not well understood for a long time.
