Spacetime-emergent ring toward tabletop quantum gravity experiments

We propose a way to discover, in tabletop experiments, spacetime-emergent materials, that is, materials holographically dual higher-dimensional quantum gravity systems under the AdS/CFT. The emergence of holographic spacetime is verified by mathematical imaging transform response function on material. consider theories one-dimensional ring-shaped material and compute scalar source locally put at point ring. When theory has dual, low-temperature phase exhibits distinct difference from ordinary materials: can look into emergent curved provides an image as if wave had propagated there. Therefore experimental signature emergence. also estimate temperature, ring size, frequency usable with example critical material, ${\mathrm{TlCuCl}}_{3}$.
