概要

• 論文の詳細を見る

• The metastable phase (trans-cisoid) of cis-polyacetylene is expected to decay into the ground state (cis-transoid) through the formation of a polaron. In the present paper, the quantum nucleation rate of the polaron is analyzed within the framework of the WKB approximation. The electronic degrees of freedom are integrated exactly, by which the field theoretical equation of motion is reduced to that for the polaron size alone. Then the quantum nucleation rate for this coordinate is evaluated. It is shown that the nucleation rate thus obtained is much larger than that previously speculated.
