Polarons in Trans-Polyacetylene and Polyyne Chains

The polaron formation in trans‐polyacetylene as well as polyyne chains is investigated in the framework of the finite‐band scheme. The physical characteristics of polarons (spin, charge, formation energy, width, binding energy) are calculated. The bipolaron, tripolaron, and polarexciton states in po...

Zusammenfassung:	The polaron formation in trans‐polyacetylene as well as polyyne chains is investigated in the framework of the finite‐band scheme. The physical characteristics of polarons (spin, charge, formation energy, width, binding energy) are calculated. The bipolaron, tripolaron, and polarexciton states in polyyne are considered. A self‐consistent discrete analysis of polaron states is presented. Comparison between the finite‐band and discrete calculations is done. [Russian Text Ignored]
