标题： Gravitino Condensates in the Early Universe and Inflation

摘要： 我们回顾了在早期宇宙中通过超希格斯效应形成重力子凝聚体的研究。 这是一种使早期宇宙膨胀并打破局部超对称性（超引力）的场景，完全独立于任何与外部物质的耦合。 与（全局）超对称性破缺相关的金斯托因模式被重力子场“吸收”，重力子因此变得有质量（通过其自身的真空凝聚）并动态地打破局部超对称性（超引力）。 重力子凝聚体与暴胀最自然的关联是通过一种星罗宾斯基型暴胀相间接实现的。 在破缺超引力相中，通过在弯曲时空背景中积分出大质量重力子自由度而引起的重力子凝聚体的（量子）有效作用的高阶曲率修正，导致了一个标量模式，从而引发了宇宙的暴胀。 该场景在参数的自然且现象学相关范围内与普朗克数据现象学一致，即超对称性破缺能标为大统一理论值以及动态诱导的重力子质量。 显示英文摘要

摘要： We review work on the formation of gravitino condensates via the super-Higgs effect in the early Universe. This is a scenario for both inflating the early universe and breaking local supersymmetry (supergravity), entirely independent of any coupling to external matter. The goldstino mode associated with the breaking of (global) supersymmetry is "eaten" by the gravitino field, which becomes massive (via its own vacuum condensation) and breaks the local supersymmetry (supergravity) dynamically. The most natural association of gravitino condensates with inflation proceeds in an indirect way, via a Starobinsky-inflation-type phase. The higher-order curvature corrections of the (quantum) effective action of gravitino condensates induced by integrating out massive gravitino degrees of freedom in a curved space-time background, in the broken-supergravity phase, are responsible for inducing a scalar mode which inflates the Universe. The scenario is in agreement with Planck data phenomenology in a natural and phenomenologically-relevant range of parameters, namely Grand-Unified-Theory values for the supersymmetry breaking energy scale and dynamically-induced gravitino mass.
