标题： On optical spectroscopy of molecular junctions

摘要： 我们比较用于描述分子结中光学响应的理论技术，并讨论它们在模拟此类系统拉曼光谱中的应用。 希尔伯特空间与李乌维尔空间，以及准粒子与多体态表述的优缺点被讨论。 识别了这些方法的共同起源以及不同表述中所使用的不同近似。 显示英文摘要

摘要： We compare theoretical techniques utilized for description of optical response in molecular junctions, and their application to simulate Raman spectroscopy in such systems. Strong and weak sides of the Hilbert vs. Liouville space, as well as quasiparticles vs. many-body states, formulations are discussed. Common origins of the methodologies and different approximations utilized in different formulations are identified.
