AI总结:

该研究探讨全局双曲时空中自由标量场标准子空间的模哈密顿量与两点函数的关联,复现了已有公式,给出基于KMS条件的更直接推导,并将结果推广到一般CCR代数。

摘要:

我们研究全局双曲时空中任意高斯态下自由标量场标准子空间对应的模哈密顿量,阐明其与该理论两点函数的关联。针对模哈密顿量在子空间上的限制,我们复现了此前由Peschel、Casini和Huerta得到的公式。我们还展示了如何从KMS条件更直接地得到相同结果,并将结论推广至一般CCR代数。

英文摘要:

We consider the modular Hamiltonian associated to standard subspaces for a free scalar field in a globally hyperbolic spacetime in an arbitrary Gaussian state. We show how the modular Hamiltonian is related to the two-point function of the theory. For the restriction of the modular Hamiltonian to the subspace, we recover formulas that were obtained previously by Peschel, Casini and Huerta. We also show how the same results can be obtained more directly from the KMS condition, and generalize our results to general CCR algebras.
