框架BPS状态、模量动力学和跨壁

Framed BPS States, Moduli Dynamics, and Wall-Crossing

Sungjay Lee, Piljin Yi

摘要:

在强耦合N=2的Seiberg-Witten理论中,我们建立了BPS双子的超对称低能动力学方程,并导出了其跨壁公式.对于由一个重核态和n个探测(晕)双子组成的BPS态,我们得到了一个可靠的具有3 n个玻色子坐标和4 n个费米超伴子的超对称模动力学。吸引相互作用通过一组超对称势项捕获,其细节仅取决于电荷和N=2理论的特殊Kaehler数据。控制近似的小参数不是电耦合,而是芯和探针之间的质量比,以及到探针和芯的中心荷对齐的边缘稳定壁的距离。量子化动力学,我们构造BPS束缚态,并从第一性原理推导出原始和半原始的跨壁公式。我们推测线运营商和达布坐标的应用程序,也关于扩展到超重力设置。

英文摘要:

We formulate supersymmetric low energy dynamics for BPS dyons in strongly-coupled N=2 Seiberg-Witten theories, and derive wall-crossing formulae thereof. For BPS states made up of a heavy core state and n probe (halo) dyons around it, we derive a reliable supersymmetric moduli dynamics with 3n bosonic coordinates and 4n fermionic superpartners. Attractive interactions are captured via a set of supersymmetric potential terms, whose detail depends only on the charges and the special Kaehler data of the underlying N=2 theories. The small parameters that control the approximation are not electric couplings but the mass ratio between the core and the probe, as well as the distance to the marginal stability wall where the central charges of the probe and of the core align. Quantizing the dynamics, we construct BPS bound states and derive the primitive and the semi-primitive wall-crossing formulae from the first principle. We speculate on applications to line operators and Darboux coordinates, and also about extension to supergravity setting.
