A charge model as an effective model of one-dimensional Hubbard and extended Hubbard systems: its application to linear optical spectrum calculations in large systems based upon many-body Wannier functions

Shu Ohmura, Akira Takahashi, Kaoru Iwano +5

We propose an effective model called the "charge model", for the half-filled one-dimensional Hubbard and extended Hubbard models. In this model, spin-charge separation, which has b…

Photoexcitation of a polarization-inverted domain from the charge-ordered ferroelectric ground state of (TMTTF) $_{2}$ PF $_{6}$

T. Yamaguchi, K. Asada, H. Yamakawa +5

We theoretically revealed that a weak photoexcitation achieves the electric polarization-inversion with approximately $18%$ of all the charges, which was interpreted as a superimp…
