Abstract
Tight-binding electron-ion dynamics of carbon chains pumped by intense laser pulses are performed to study the interactions between monatomic carbon chains and lasers. Laser-induced distortions of carbon chains, which are enhanced by a long wavelength laser, are investigated. The carbon chains with a strong laser beam focused on one terminal are simulated to study the disturbance of electronic states. By the superposition of delocalized π band states, the disturbance propagates from the illuminated area to the non-illuminated area in a velocity of about 106 m/s at 0 K, and this velocity is weakened at room temperature due to the localization effect of thermal fluctuation.
