Abstract

<p>A phenomenon in which an electronic structure of a solid is changed by visible-light irradiation is called a photoinduced phase transition. In correlated electron systems with strong Coulomb repulsion among electrons, charge carriers generated by visible-light irradiation can cause the changes in the surrounding electron system through strong electron-electron interactions, sometimes resulting in an ultrafast electronic phase transition. We have been trying to generate charge carriers by a nearly monocyclic strong electric-field pulse called a terahertz pulse and realize a similar electronic phase transition. In this paper, as a typical example of such phase transitions, we report an electric-field-induced ultrafast insulator-metal transition in an organic molecular compound.</p>
