Proper Time Oscillators as Physical Relational Clocks: Toward A Many-Clock Extension of the Page–Wootters Mechanism

The Problem of Time in canonical quantum gravity arises from the timeless structure of the Wheeler--DeWitt equation. While the Page--Wootters mechanism shows how relational dynamics can emerge by conditioning a global quantum state on an internal clock, the physical clock is gene...
