从Euler-Arnold方程得到的共形场论复杂性

Conformal field theory complexity from Euler-Arnold equations

Mario Flory, Michal P. Heller

摘要:

在量子场论中定义复杂性是一项困难的任务,主要的挑战涉及超越自由模型和相关的高斯态和运算。一个采取这个问题是考虑共形场论在1+1维和我们的工作是一个全面的研究状态和运营商的复杂性在其能量动量张量的普遍部门。统一的概念思想是欧拉-阿诺德方程及其积分-微分推广,这保证了两个通用状态或感兴趣的变换之间的优化问题的适定性。目前的工作提供了一个深入的讨论,在arXiv:2005.02415中报告的结果和在其推导中使用的技术。其中最重要的主题,我们涵盖的是使用微分正则化,积分微分方程的解决方案描述Fubini研究状态的复杂性和探索的基础几何。

英文摘要:

Defining complexity in quantum field theory is a difficult task, and the main challenge concerns going beyond free models and associated Gaussian states and operations. One take on this issue is to consider conformal field theories in 1+1 dimensions and our work is a comprehensive study of state and operator complexity in the universal sector of their energy-momentum tensor. The unifying conceptual ideas are Euler-Arnold equations and their integro-differential generalization, which guarantee well-posedness of the optimization problem between two generic states or transformations of interest. The present work provides an in-depth discussion of the results reported in arXiv:2005.02415 and techniques used in their derivation. Among the most important topics we cover are usage of differential regularization, solution of the integro-differential equation describing Fubini-Study state complexity and probing the underlying geometry.
