拓扑奇点的量子动力学：Feynman影响泛函方法
Quantum Dynamics of Topological Singularities: Feynman's Influence Functional Approach
摘要：
从Bardeen-Cooper-Schrieffer（BCS）的费米子超流体微观理论出发，通过扩展Feynman的影响泛函方法，引入横向力，我们证明了涡旋动力学可以自然地遵循.横向和纵向的影响有一个惊人的相互独立性：前者具有拓扑起源，是不敏感的细节，而后者对应于众所周知的阻尼内核取决于细节。
英文摘要：
Starting from the microscopic theory of Bardeen-Cooper-Schrieffer (BCS) for the fermionic superfluids, we show that the vortex dynamics can be followed naturally by extending Feynman's influence functional approach to incorporate the transverse force. There is a striking mutual independence of the transverse and longitudinal influences: The former has the topological origin and is insensitive to details, while the latter corresponds to the well-known damping kernel depending on details.
