论文摘要
膜成核是Schwinger效应的较高维度类似物，是真空衰减的有用玩具模型。虽然非扰动效应，但成核速率的计算仅在田间理论中的弱耦合下才实现。在这里，我们使用ADS/CFT二元性计算球形膜的成核速率，因此自然包括强耦合的效果。更确切地说，我们认为球形膜的成核与反对称张量场耦合，这一过程使真空不稳定的过程在磁场强度的临界值之上。我们使用广告的各种叶子在平坦和DE Sitter空间中分析膜的创造。这是通过Instanton方法完成的，其中成核的速率由半古典的壳欧几里得作用支配。我们的发现概括了全息造型的schwinger效应，并为Coleman-de Luccia Instantons介导的全息假真空衰减提供了步骤。
Membrane nucleation, a higher dimensional analog of the Schwinger effect, is a useful toy model for vacuum decay. While a non-perturbative effect, the computation of nucleation rates has only been accomplished at weak coupling in the field theory. Here we compute the nucleation rates of spherical membranes using AdS/CFT duality, thus naturally including the effects of strong coupling. More precisely, we consider the nucleation of spherical membranes coupled to an antisymmetric tensor field, a process which renders the vacuum unstable above a critical value of the field strength. We analyze membrane creation in flat and de Sitter space using various foliations of AdS. This is accomplished via instanton methods, where the rate of nucleation is dominated by the semi-classical on-shell Euclidean action. Our findings generalize the holographic Schwinger effect and provide a step toward holographic false vacuum decay mediated by Coleman-De Luccia instantons.
