Abstract

Ultrafast photoinduced transitions among three phases-charge density wave (CDW), Mott-Hubbard insulator, and metal-were investigated in an iodine (I)-bridged platinum (Pt) compound by femtosecond reflection spectroscopy. For a weak photoexcitation, CDW phase over 70 Pt sites is converted to Mott-Hubbard phase by one photon. Such large conversion efficiency makes possible the complete and transient transition from CDW to Mott-Hubbard phase. For a strong excitation, the low-energy spectral weight is increased, suggesting a conversion to a metallic state.
