一个广义动量/复杂性对应

A Generalized Momentum/Complexity Correspondence

J. L. F. Barbon, J. Martin-Garcia, M. Sasieta

摘要:

全息的复杂性,在复杂性=体积处方的幌子下,配备了其增长率和物质在体积中的平均下落动量之间的自然对应关系。这种动量/复杂性的对应关系可以与广义相对论的动量约束的综合版本相关联。在本文中,我们提出了一个推广,使用完整的Codazzi方程作为出发点,它成功地占纯粹的引力对下落动量的贡献。所提出的公式是明确检查在真空爱因斯坦方程的精确pp波解。

英文摘要:

Holographic complexity, in the guise of the Complexity = Volume prescription, comes equipped with a natural correspondence between its rate of growth and the average infall momentum of matter in the bulk. This Momentum/Complexity correspondence can be related to an integrated version of the momentum constraint of general relativity. In this paper we propose a generalization, using the full Codazzi equations as a starting point, which successfully accounts for purely gravitational contributions to infall momentum. The proposed formula is explicitly checked in an exact pp-wave solution of the vacuum Einstein equations.
