Time and classical equations of motion from quantum entanglement via the Page and Wootters mechanism with generalized coherent states

Discussions about the role of time in quantum mechanics are often detached from the corresponding classical limit. Here, the authors provide the Page and Wootters mechanism with a classical limit using the large-N approach based on generalized coherent states, without the need to introduce time meas...
