具有三个弦模的BMN两点函数的非负性

Non-Negativity of BMN Two-Point Functions With Three String Modes

Bao-ning Du, Min-xin Huang

摘要:

最近,我们提出了一个新的pp波全息字典条目,它等同于自由$\mathcal{N}=4$ super-Yang-Mills理论中的Berenstein-Maldacena-Nastase(BMN)两点函数与无限曲率极限下相应的无张力弦之间的量子幺正跃迁振幅的范数平方,对于不超过三个弦模式在不同的横向方向的情况。一个看起来非常重要的非平凡的结果,特别是在三个弦模的情况下,是BMN两点函数在任何更高的亏格对任何模数的非负性。在本文中,我们进一步进行了详细的计算的BMN两点函数与三个弦模式亏格2,并明确地证明,他们总是非负的,通过大多数广泛的数值测试。

英文摘要:

Recently, we proposed a novel entry of the pp-wave holographic dictionary, which equated the Berenstein-Maldacena-Nastase (BMN) two-point functions in free $\mathcal{N}=4$ super-Yang-Mills theory with the norm squares of the quantum unitary transition amplitudes between the corresponding tensionless strings in the infinite curvature limit, for the cases with no more than three string modes in different transverse directions. A seemingly highly non-trivial conjectural consequence, particularly in the case of three string modes, is the non-negativity of the BMN two-point functions at any higher genus for any mode numbers. In this paper, we further perform the detailed calculations of the BMN two-point functions with three string modes at genus two, and explicitly verify that they are always non-negative through mostly extensive numerical tests.
