论文摘要

众所周知,用数百个Kähler模量在IIB型弦线型压实中实现完整的模量稳定。这不仅归因于计算复杂性与模量数的非常快速增加,而且还归因于标量势一般而言仅取决于超级重力变量的事实。实际上,超级性手性坐标是4周期体积模量,但kähler电位是2循环模量的明确函数,并且这两个变量之间的反转是不可能的。 In this paper we propose a general method to fix all type IIB Kähler moduli in a systematic way by working directly in terms of 2-cycle moduli: on one side we present a `master formula' for the scalar potential which can depend on an arbitrary number of Kähler moduli, while on the other we perform a computer-based search for critical points, introducing a hybrid Genetic/Clustering/Amoeba algorithm and other computational技术。这使我们能够重现几个已知的最小值,但也可以发现KKLT和LVS模型的新示例,以及新型的LVS Minima,而没有对角线Del Pezzo除数和混合真空吸尘器,这些真空与KKLT和LVS Solutions具有与KKLT和其他功能。

Achieving full moduli stabilisation in type IIB string compactifications for generic Calabi-Yau threefolds with hundreds of Kähler moduli is notoriously hard. This is due not just to the very fast increase of the computational complexity with the number of moduli, but also to the fact that the scalar potential depends in general on the supergravity variables only implicitly. In fact, the supergravity chiral coordinates are 4-cycle volume moduli but the Kähler potential is an explicit function of the 2-cycle moduli and inverting between these two variables is in general impossible. In this paper we propose a general method to fix all type IIB Kähler moduli in a systematic way by working directly in terms of 2-cycle moduli: on one side we present a `master formula' for the scalar potential which can depend on an arbitrary number of Kähler moduli, while on the other we perform a computer-based search for critical points, introducing a hybrid Genetic/Clustering/Amoeba algorithm and other computational techniques. This allows us to reproduce several known minima, but also to discover new examples of both KKLT and LVS models, together with novel classes of LVS minima without diagonal del Pezzo divisors and hybrid vacua which share some features with KKLT and other with LVS solutions.
