论文摘要
为了了解扩展宇宙中时间依赖性的量子相关性，我们研究了Braneworld模型中时间依赖的纠缠熵。如果我们考虑到由统一分布的开弦引起的广义弦云几何形状，则对Braneworld的宇宙学会导致标准的Friedmann-Lema- Robertson-Robertson-Walker-Walker宇宙学具有各种物质内容。在双场理论方面，开放字符串被重新解释为基本物质，而黑洞质量则对应于无质量规玻色的激发能。在这项工作中，我们展示了弦云的几何形状如何与各种Braneworld Cosmologie匹配，例如，永恒的通货膨胀，辐射和以物质为主的宇宙。然后，我们研究了纠缠熵如何在那些不断扩展的宇宙中演变。
To understand the time-dependent quantum correlation in expanding universes, we study the time-dependent entanglement entropy in the braneworld model. If we take into account a generalized string cloud geometry caused by uniformly distributed open strings, cosmologies on the braneworld result in the standard Friedmann-Lemaître-Robertson-Walker cosmologies with various matter contents. On the dual field theory side, open strings are reinterpreted as a fundamental matter, while the black hole mass corresponds to the excitation energy of massless gauge bosons. In this work, we show how the string cloud geometry is matched to various braneworld cosmologie,s for example, eternal inflation, radiation-, and matter-dominated universes. Then, we investigate how the entanglement entropy evolves in those expanding universes.
