We present a gauge-invariant treatment of singularity resolution using quantum gravity techniques. Our analysis reveals many novel features of quantum geometry which were till now hidden in models based on non-gauge-invariant discretizations. Quantum geometric effects result in a non-singular bounce which is generically asymmetric with effective constants getting rescaled beyond the singularity, and minimally coupled matter behaving as non-minimally coupled. These ramifications of quantum geometry open a rich avenue for potential phenomenological signatures.

来自圈量子引力的规范不变反弹

我们使用量子引力技术提出了奇点分辨率的规范不变处理。我们的分析揭示了量子几何的许多新特征，这些特征迄今为止隐藏在基于非规范不变离散化的模型中。量子几何效应导致非奇异反弹，它通常是不对称的，有效常数被重新调整超过奇点，并且最小耦合的物质表现为非最小耦合。量子几何的这些分支为潜在的现象学特征开辟了一条丰富的途径。
