我们考虑 IIB 型弦理论中几何形状的 1/2 BPS 激发，可以根据 Lin、Lunin 和 Maldacena (LLM) 的规定映射到自由费米子构型。结果表明，只要费米子概率密度超过 1 或为负值，就会大量出现闭合的类时曲线。因此，费米子相空间中泡利不相容原理的违反与对偶几何中因果关系的违反密切相关。
We consider 1/2 BPS excitations of geometries in type IIB string theory that can be mapped into free fermion configurations according to the prescription of Lin, Lunin and Maldacena (LLM). It is shown that whenever the fermionic probability density exceeds one or is negative, closed timelike curves appear in the bulk. A violation of the Pauli exclusion principle in the phase space of the fermions is thus intimately related to causality violation in the dual geometries.
