Time as an Observable
J. Oppenheim, B. Reznik, W. G. Unruh
The role of time in quantum mechanics is discussed. The differences between ordinary observables and an observable which corresponds to the time of an event is examined. In particu…

Time-of-Arrival States
J. Oppenheim, B. Reznik, W. G. Unruh
Although one can show formally that a time-of-arrival operator cannot exist, one can modify the low momentum behaviour of the operator slightly so that it is self-adjoint. We show…

When does a Measurement or Event Occur
J. Oppenheim, B. Reznik, W. G. Unruh
Within quantum mechanics it is possible to assign a probability to the chance that a measurement has been made at a specific time t. However, the interpretation of such a probabili…
