在费曼路径积分理论的框架内,我们对低维受限介质中Frohlich极化子的基态性质提供了一个统一的认识。我们采用的模型包括一个电子沉浸在该领域的散装LO声子和有界的各向异性抛物势盒,其障碍的斜率可以调整,以产生明确的跟踪Frohlich相互作用,包括散装和所有低维几何配置的一般利益。
Within the framework of the Feynman path integral theory, we provide a unified insight into ground-state properties of the Frohlich polaron in low-dimensionally confined media. The model that we adopt consists of an electron immersed in the field of bulk LO phonons and bounded within an anisotropic parabolic potential box, whose barrier slopes can be tuned so as to yield an explicit tracking of the Frohlich interaction encompassing the bulk and all low-dimensional geometric configurations of general interest.
