反射熵与双曲弦顶点之间的联系
Connections between reflected entropies and hyperbolic string vertices
摘要:
本文建立了CFT $_{2}$中多体混合态的反射熵与闭弦场论(CSFT)的双曲弦顶点之间的联系。我们发现,反射面,这是大量的反射熵,共享相同的黎曼曲面的双曲弦顶点。这一观察使我们能够建立反射熵和双曲弦顶点之间的定量关系。我们用几个例子来说明这种联系。因此,我们提出时空结构可以直接从双曲弦顶点产生。双曲弦顶点方法的优点是我们有一个动力学方程,Batalin-Vilkoviski主方程,来控制生成过程。
英文摘要:
In this paper, we establish connections between reflected entropies of multipartite mixed states in CFT$_{2}$ and hyperbolic string vertices of closed string field theory (CSFT). We show that the reflected surfaces, which are bulk duals of the reflected entropies, share the same Riemann surfaces with the hyperbolic string vertices. This observation enables us to build quantitative relations between the reflected entropies and hyperbolic string vertices. We illustrate the connections with several examples. Consequently, we propose that spacetime structure could be directly generated from the hyperbolic string vertices. The advantage of the hyperbolic string vertices approach is that we have a dynamical equation, the Batalin-Vilkoviski master equation, to control the generating process.
