摘要翻译：
推广重整化群方法，考虑费米子气体相互作用的延迟效应，重新研究了一维类Peierls态的量子和经典性质。对于无自旋费米子和自旋1/2费米子与分子内或分子间声子相互作用的模型，在任意声子频率下，确定了半填充Peierls能隙的量子修正。在弱耦合条件下阐明了量子-经典跃迁的性质。

英文摘要：
An extension of the renormalization group method that includes the effect of retardation for the interactions of a fermion gas is used to re-examine the quantum and classical properties of Peierls- like states in one dimension. For models of spinless and spin-1/2 fermions interacting with either intra or intermolecular phonons the quantum corrections to the Peierls gap at half-filling are determined at arbitrary phonon frequency. The nature of quantum-classical transitions is clarified in weak coupling.
