通过将反膜放置在扭曲的喉部，可以在通量几何形状中创建亚稳态、超对称性破缺的构型。通过规范/重力对偶性，这种配置应该被解释为双场理论中的超对称破缺状态。在本文中，我们扰动地确定了与放置在级联扭曲变形圆锥几何形状尖端的 D3 膜探针相对应的渐近超重力解，该探针与 SU(N+M) x SU(N) 规范理论是对偶的。反膜的逆反应具有引入假想的反自对偶通量、挤压空间的致密部分并迫使膨胀子运行的作用。利用全息重正化对级联几何的推广，我们根据超重力场的渐近值确定了对偶场理论中算子的期望值。
Metastable, supersymmetry-breaking configurations can be created in flux geometries by placing antibranes in warped throats. Via gauge/gravity duality, such configurations should have an interpretation as supersymmetry-breaking states in the dual field theory. In this paper, we perturbatively determine the asymptotic supergravity solutions corresponding to D3-brane probes placed at the tip of the cascading warped deformed conifold geometry, which is dual to an SU(N+M) x SU(N) gauge theory. The backreaction of the antibranes has the effect of introducing imaginary anti-self-dual flux, squashing the compact part of the space and forcing the dilaton to run. Using the generalization of holographic renormalization to cascading geometries, we determine the expectation values of operators in the dual field theory in terms of the asymptotic values of the supergravity fields.
