Photocontrollable Mixed-Valent States in Platinum-Halide Ladder Compounds

Photocontrollable Mixed-Valent States in Platinum-Halide Ladder Compounds

Employing a two-orbital extended Peierls⁻Hubbard model, we demonstrate the photomanipulation of mixed-valent states in platinum-halide ladder compounds. There are two types of interchain valence arrangements, namely in-phase and out-of-phase types. The conversion of the in-phase structure...
