In this review, physical motivation and various numerical techniques for the examination are presented. Then, we summarize our DMRG analysis for photoinduced phenomena in 1D Mott insulators and other transition metal oxides. Close connection between DMRG and key aspects of quantum information such as entanglement is also addressed. << 收起
