Low-energy structure of the intertwining double-chain ferrimagnets A_3_Cu_3_(PO_4_)_4_ (A=Ca,Sr,Pb)
Shoji Yamamoto, Jun Ohara
Motivated by the homometallic intertwining double-chain ferrimagnets A_3_Cu_3_(PO_4_)_4_ (A=Ca,Sr,Pb), we investigate the low-energy structure of their model Hamiltonian H=\sum_n_[…
Nonlinear lattice relaxation of photoexcited diplatinum-halide chain compounds
Jun Ohara, Shoji Yamamoto
In order to reveal the relaxation mechanism of photogenerated charge-transfer excitations in quasi-one-dimensional halogen-bridged diplatinum complexes, we calculate the low-lying…
Photoinduced infrared absorption of quasi-one-dimensional halogen-bridged binuclear transition-metal complexes
Jun Ohara, Shoji Yamamoto
We investigate the optical conductivity of photogenerated solitons in quasi-one-dimensional halogen-bridged binuclear transition-metal MMX complexes with particular emphasis on a c…
Photoinduced Absorption Spectra of Halogen-Bridged Binuclear Metal Complexes: Possible Contrast between R_4_[Pt_2_(P_2_O_5_H_2_)_4_X]nH_2_O and Pt_2_(CH_3_CS_2_)_4_I
Jun Ohara, Shoji Yamamoto
The optical conductivity of photogenerated solitons in quasi-one-dimensional halogen-bridged binuclear metal (MMX) complexes is investigated with particular emphasis on a compariso…
Soliton-induced optical absorption of halogen-bridged mixed-valence binuclear metal complexes
Jun Ohara, Shoji Yamamoto
Employing the one-dimensional single-band extended Peierls-Hubbard model, we investigate optical conductivity for solitonic excitations in halogen-bridged binuclear metal (MMX) com…
