自旋玻色子哈密顿量与分子二聚体的光吸收
Spin-Boson Hamiltonian and Optical Absorption of Molecular Dimers
摘要：
通过计算Bloch和Husimi投影，分析了自旋玻色子哈密顿量破缺后的本征态.将本征态分析与非对称二聚体构型的吸收带计算相结合，该构型由具有不同激发能和光学跃迁矩阵元的单体构成。获得了具有规则和不规则精细结构的吸收带，并与光谱中绝热分支从共存到混合的过渡有关。结果表明，自旋状态之间的相关性允许不同的光学不对称性的吸收带之间的插值。
英文摘要：
An analysis of the eigenstates of a symmetry-broken spin-boson Hamiltonian is performed by computing Bloch and Husimi projections. The eigenstate analysis is combined with the calculation of absorption bands of asymmetric dimer configurations constituted by monomers with nonidentical excitation energies and optical transition matrix elements. Absorption bands with regular and irregular fine structures are obtained and related to the transition from the coexistence to a mixing of adiabatic branches in the spectrum. It is shown that correlations between spin states allow for an interpolation between absorption bands for different optical asymmetries.
