论文摘要
我们讨论了IIA弦理论在具有O2/O6-planes到三个维度的G2固体空间上的IIA弦理论的通量压缩，并找到了两类的解决方案：1）NOCALE MINKOWSKI真空吸尘器来自NSNS 3型磁通量和RR 4型通量。 2）通过添加罗马人质量，我们发现广告$ _3 $真空吸尘器可以将广告比例完全与KK尺度完全解耦，而解决方案则以可调的弱耦合和较大的体积为单位。对于ADS $ _3 $真空吸尘器，我们只有适当的3D说明（即涂抹的Erientifold描述），例如来自Fluxes和O6-planes的IIA Moduli稳定的4D类似物。 3D描述表明，具有非紧密模量空间的模量可以在经典级别稳定。对于两种类型的真空吸尘器，我们都可以具有超对称性。
We discuss flux compactifications of IIA string theory on G2 holonomy spaces with O2/O6-planes to three dimensions and find two classes of solutions: 1) No-scale Minkowski vacua from NSNS 3-form fluxes and RR 4-form fluxes. 2) By adding Romans mass we find AdS$_3$ vacua for which the AdS scale can be decoupled completely from the KK scale while the solution is at tunable weak coupling and large volume. For the AdS$_3$ vacuum we only have a proper 3D description (i.e. smeared orientifold description) of the solution like the 4D analogue of IIA moduli stabilization from fluxes and O6-planes. This 3D description reveals that moduli with non-compact moduli spaces can be stabilized at the classical level. For both types of vacua we can have supersymmetry or not.
