Outline

Ultrafast manipulation technique to provide drastic changes of physical properties (magnetic, dielectric, conductive, optical properties) of condensed matters with external fields by inducing large amplitude motions of ionic atom and electron spin are expected to be breakthrough in ultrafast electronics for meeting social demands. In this study, we develop a novel technique that confines ultra-intense terahertz light pulses in nanoscale area and extremely enhances its field strength, enables us to study unexplored electric- or magnetic-field induced phenomena of new materials that contribute to the development of ultimate high-speed electronic devices.
