Abstract
摘要 |
Classical spaces with geometries are shown to emerge on boundaries of randomly connected tensor networks. We give the explicit solvable examples of emergent flat tori in arbitrary dimensions, and the general curved cases are also considered. The perturbative dynamics is shown to be described by an effective action which is invariant under the spatial diffeomorphism due to the underlying orthogonal group symmetry of the tensor networks. It is also shown that there are various phase transitions among spaces, such as the transition between extended and point-like spaces. |
