Coexistence of Charge Order and Spin-Peierls Lattice Distortion in One-Dimensional Organic Conductors
Makoto Kuwabara, Hitoshi Seo, Masao Ogata
The electronic properties of quarter-filled organic materials showing spin-Peierls transition are investigated theoretically. By studying the one-dimensional extended Peierls-Hubba…
Electronic and Lattice Dynamics in The Photoinduced Ionic-to-Neutral Phase Transition in a One-Dimensional Extended Peierls-Hubbard Model
Naoyuki Miyashita, Makoto Kuwabara, Kenji Yonemitsu
Real-time dynamics of charge density and lattice displacements is studied during photoinduced ionic-to-neutral phase transitions by using a one-dimensional extended Peierls-Hubbard…
Polaron versus bipolaron in conducting polymers: a density matrix renormalization group study
Makoto Kuwabara, Yukihiro Shimoi, Shuji Abe
Competition between polaron and bipolaron inconjugated polymers with nondegenerate ground state is systematically studied in the extended Hubbard-Peierls model with the symmetry-br…
Interchain Pair Hopping of Solitons and Polarons via Dopants in Polyacetylene
Makoto Kuwabara, Shuji Abe, Yoshiyuki Ono
Interchain hopping of solitons and polarons in polyacetylene is studied by numerical simulation of their motion under an electric field. Use is made of the Su-Schrieffer-Heeger mod…
Semi-Phenomenological Analysis of Dynamics of Nonlinear Excitations in One-Dimensional Electron-Phonon System
Makoto Kuwabara, Akira Terai, Yoshiyuki Ono
The structure of moving nonlinear excitations in one-dimensional electron-phonon systems is studied semi-phenomenologically by using an effective action in which the width of the n…
Dynamics of an Acoustic Polaron in One-Dimensional Electron-Lattice System
Y. Arikabe, M. Kuwabara, Y. Ono
The dynamical behavior of an acoustic polaron in typical non-degenerate conjugated polymer, polydiacetylene, is numerically studied by using Su-Schrieffer-Heeger's model for the on…
