Recent studies on the light-induced phenomena in condensed matter systems and related numerical tools

Recent studies of light–matter interaction reveal that light can significantly manipulate materials’ properties. For example, recent experiments demonstrated light-induced phenomena such as light-enhanced superconductivity, ferroelectricity, topological phase transition, and light-driven quantum transport in condensed matter systems. With these experimental observations, various theoretical studies tried to provide possible microscopic mechanisms such as nonlinear phonon interaction, displacive excitation of coherent phonon, and Floquet engineering. These comprehensive experimental and theoretical studies suggested the possibility of light-controlled devices as an application. This review summarizes recently reported light-induced phenomena and related microscopic mechanisms. In addition, the numerical tools for the simulation of light-induced dynamics are introduced.
