Abstract

The strong-light field effect of (TMTTF)2AsF6 was investigated utilizing 1.5-cycle, 7-fs infrared pulses. The ultrafast (∼20fs) and large (∼40%) response of the plasmalike reflectivity edge (∼0.7eV) was analyzed by the changes in ωp=ne2/(∞0m) (n: number of charges in the frac14-filled band; m: mass of charge; ∞,0: dielectric constants for high frequency and vacuum; e: elementary charge). The 3% reduction in ωp is attributed to the 6% increase in m. Furthermore, 20 fs oscillation of ωp in the time domain indicates that the plasmalike edge is affected by the charge gap (∼0.2eV) nature. Theoretical calculations suggest that the Coulomb repulsion plays an important role in the increase in m.
