Abstract

We present an ab initio GW calculation to study dynamical effects on an organic compound (TMTSF)2 PF6. Calculated polarized reflectivities reproduce experimental plasma edges at around 0.2 eV for E∥b′ and 1.0 eV for E∥a. The low-energy plasmons come out from the low-energy narrow bands energetically isolated from other higher-energy bands, and affect the low-energy electronic structure via the GW-type self-energy. Because of the quasi-one-dimensional band structure, a distinct plasmaron state is observed along the Y-Γ line and a large plasmon-induced electron scattering is found in the low-energy occupied states along the X-M line.
