Dynamical properties of photoexcited states in one-dimensional dimerized Mott insulators |
 |
Nobuya Maeshima |
| Dynamical properties of photoexcited states are theoretically studied in a one-dimensional Mott insulator dimerized by the spin-Peierls instability. Numerical calculations combined with a perturbative analysis have revealed that the lowest photoexcited state without nearest-neighbor interaction corresponds to an interdimer charge transfer excitation that belongs to dispersive excitations. The adiabatic potential of this excited state as a function of the lattice dimerization has demonstrated that the dimerized phase is destabilized by the photoexcitation from the ground state to this excited state. We also discuss the purely electronic origin of midgap states that are observed in a latest photoexcitation experiment of an organic spin-Peierls compound, K-TCNQ (potassium-tetracyanoquinodimethane). |
