我们继续研究耦合到两个球对称标量场的球对称圈量子引力，其中一个标量场充当时钟。由于后者的存在，我们可以定义一个真正的哈密顿理论。球对称的上下文允许执行精确的详细计算。在这里，我们研究的理论区域的大值的径向坐标。这使我们能够详细地定义理论的真空并研究其量子态，从而产生一个量子时空的量子场论，它与经典时空的通常处理方法相联系。
We continue our work on the study of spherically symmetric loop quantum gravity coupled to two spherically symmetric scalar fields, one which acts as a clock. As a consequence of the presence of the latter, we can define a true Hamiltonian for the theory. The spherically symmetric context allows to carry out precise detailed calculations. Here we study the theory for regions of large values of the radial coordinate. This allows us to define in detail the vacuum of the theory and study its quantum states, yielding a quantum field theory on a quantum space time that makes contact with the usual treatment on classical space times.
