| Outline of Final Research Achievements |
Elementary particles with electric charges, such as protons and electrons, are fundamental particles, forming our world. In contrast, magnetic monopoles with magnetic charges, i.e., particles as sources or sinks of magnetic field, have not been identified so far. The classical electromagnetism is therefore structured under assumption of their non-existence. However, it is theoretically proposed that we can create fictitious magnetic monopoles in materials by utilizing the geometric phase of electrons. In this research project, we have focused on topology of spin textures and realized emergence of magnetic monopoles and novel electromagnetic effects associated with their pair-annihilation dynamics.
