球对称量子引力中的动力学和纠缠

Dynamics and entanglement in spherically symmetric quantum gravity

Viqar Husain, Daniel R. Terno

摘要:

球对称的引力-标量场系统为探索引力坍缩及其在量子引力中的后果提供了一个自然的背景。在一个规范的方法,我们给出的哈密顿算子的建设,和半经典状态的约束自由的数据达到峰值。这样的状态提供了物理状态的明确示例。我们还表明,物质引力纠缠是物理状态的固有特征,无论是否有一个黑洞。

英文摘要:

The gravity-scalar field system in spherical symmetry provides a natural setting for exploring gravitational collapse and its aftermath in quantum gravity. In a canonical approach, we give constructions of the Hamiltonian operator, and of semiclassical states peaked on constraint free data. Such states provide explicit examples of physical states. We also show that matter-gravity entanglement is an inherent feature of physical states, whether or not there is a black hole.
