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…
