| Resumo | |
We explore a timeless approach to quantum theory, in the form of the Page-Wootters mechanism, in which a gravitational interaction is introduced between the system and a finite-dimensional clock. The clock model used is the recently proposed quasi-ideal clock, a construction that can approximate the time-energy canonical commutation relation. We derive equations of motion for the case in which the system is in a pure and mixed state, obtaining a Schr & ouml;dinger-like equation that leads to a non-linear equation exhibiting decoherence due to the non-ideal nature of the clock and gravitational coupling. A distinctive feature of this equation is that it exhibits dependence on the system's initial conditions. (AU) | |
