The goal of this contribution is to present the properties of a class of quantum bouncing models in which the quantum bounce originates from the Dirac canonical quantization of a midi-superspace model composed of a homogeneous and isotropic background, together with small inhomogeneous perturbations. The resulting Wheeler-DeWitt equation is interpreted in the framework of the de Broglie-Bohm quantum theory, enormously simplifying the calculations, conceptually and technically. It is shown that the resulting models are stable and they never get to close to the Planck energy, where another more involved quantization scheme would have to be evoked, and they are compatible with present observations. Some physical effects around the bounce are discussed, like baryogenesis and magnetogenesis, and the crucial role of dark matter and dark energy is also studied.

弹跳量子宇宙学

此贡献的目的是介绍一类量子反弹模型的性质，其中量子反弹起源于由均质和各向同性背景组成的中超空间模型的Dirac正则量化以及较小的不均匀扰动。由此产生的Wheeler-DeWitt方程在de Broglie-Bohm量子理论的框架内进行解释，从概念上和技术上极大地简化了计算。结果表明，所得到的模型是稳定的，并且它们永远都无法接近普朗克能量，在普朗克能量中，必须要提出另一种涉及更多的量化方案，并且它们与当前的观测结果是兼容的。讨论了弹跳周围的一些物理影响，例如重生和磁生，
