Fuzzy空间上的弦模、传播子和环

String modes, propagators and loops on fuzzy spaces

Harold C. Steinacker, Juraj Tekel

摘要:

我们提出了一个系统的组织功能和运营商的模糊2球的字符串模式,这是最佳本地化的位置和动量空间。这使得分离的半经典和深量子制度的非对易量子场论,并表现出其非局域性。这种结构大大简化了回路贡献的计算,避免了振荡积分,并直接在位置空间中提供有效的作用。紫外/红外混合被理解为非局域性所产生的长弦模式的循环。该方法适用于任何量子化辛空间。

英文摘要:

We present a systematic organization of functions and operators on the fuzzy 2-sphere in terms of string modes, which are optimally localized in position and momentum space. This allows to separate the semi-classical and the deep quantum regime of non-commutative quantum field theory and exhibits its nonlocal nature. This organization greatly simplifies the computation of loop contributions, avoiding oscillatory integrals and providing the effective action directly in position space. UV/IR mixing is understood as nonlocality arising from long string modes in the loops. The method is suited for any quantized symplectic space.
