论文摘要
在这封信中，我们将使用PP-Wave轻锥字符串字段理论研究字符串场理论中的因果关系。我们将概括Ramsey方案来弦字段理论，并使用它来分析字符串字段理论过程。将使用此字符串字段理论Ramsey方案构建交互式字符串字段理论的明确特征函数。使用此特征函数将获得字符串字段理论中任何操作员的初始值和最终值之间的差异的平均值。我们将根据量子渔民信息使用量子信息理论技术来提取有关此类字符串字段理论过程的信息。
In this letter, we will investigate causality in string field theory using pp-wave light-cone gauge string field theory. We will generalize the Ramsey scheme to string field theory, and use it to analyze string field theoretical processes. An explicit characteristic function for interactive string field theory will be built using this string field theoretical Ramsey scheme. The average of the difference between the initial and final values of any operator described in string field theory will be obtained using this characteristic function. We will use the quantum information theoretical technique based on quantum fisher information to extract information about such string field theoretical processes.
