Polaronic states with Spin-Charge-Coupled Excitation in a 1D Mott Insulator K-TCNQ

Nobuya Maeshima, Kenji Yonemitsu

We discuss photogenerated midgap states of a one-dimensional (1D) dimerized Mott insulator, potassium-tetracyanoquinodimethane (K-TCNQ). Two types of phonon modes are taken into ac…
