Breathers and Photoinduced Absorption in Polyacetylene

چکیده
'The dynamics of trans-polyacetylene is studied within the adiabatic model of Su, Schrieffer, and Beeper. A single soliton has a maximum velocity, v, which can be higher than the sound velocity. A long-time simulation shows that, from an initial electron-hole pair, a soliton and antisoliton emerge with velocities +v and that a persistent breather is left behind. 'This breather may account for the high-energy intragap structure observed in photoinduced absorption, including isotope dependence.

Optical absorption from polarons in a model of polyacetylene
We present a theoretical calculation, within a continuum electron-phonon-coupled model, of the optical absorption due to polarons in polyacetylene [{CH),]. Our results can be applied to both transand cis-(CH)„, as well as potentially to other polymers (polypyroles, polyparaphenylenes) in which polarons are present. We establish that the essential signature of polaron absorption is the existence...
متن کاملOptical properties of potassium-doped polyacetylene
The optical reflectance of polyacetylene doped with high concentrations of potassium has been measured, and the optical properties estimated by Kramers–Kronig analysis. The samples, doped by a vapor-phase technique to y ≈ 0.08 and 0.18, showed strong doping-induced infrared absorption at ∼900, 1270, and 1390 cm−1. These experiments were motivated by calculations of the infrared absorption which...
متن کاملLaser-induced currents along molecular wire junctions.
The treatment of the previous paper is extended to molecular wires. Specifically, the effect of electron-vibrational interactions on the electronic transport induced by femtosecond omega+2omega laser fields along unbiased molecular nanojunctions is investigated. For this, the photoinduced vibronic dynamics of trans-polyacetylene oligomers coupled to macroscopic metallic leads is followed in a m...
متن کاملBreathers in hydrogen-bonded chains
In the framework of the one-component model for hydrogen-bonded chains developed by Zolotaryuk and Pnevmatikos [Phys. Lett. A 143 (1990) 233], we study analytically and numerically breather excitations in the continuum and the discrete-carrier limits. We demonstrate that the breathers show high-stability properties especially in the case when the on-site potential is symmetric. We also consider...
