Comment on “Arrival time in quantum mechanics” and “Time of arrival in quantum mechanics”

Physical Review A, 1999
Contrary to claims contained in papers by Grot, Rovelli, and Tate [Phys. Rev. A 54, 4676 1996)] and Delgado and Muga [Phys. Rev. A 56, 3425 (1997)], the ``time operator,'' which I have constructed [Rep. Math. Phys. 6, 361 (1974)] in an axiomatic way, is a self-adjoint operator existing in a usual Hilbert space of (nonrelativistic or relativistic ...

Arrival time distributions

Physics Letters A, 1993
Abstract A simple derivation, using Bohm trajectories, is given of Dumont and Marchioro's expression for the distribution of arrival times of transmitted particles at a point on the far side of a 1D barrier. Calculated distributions are presented and the “quantum speed-up effect” discussed from the Bohm trajectory viewpoint.

Poisson Arrivals See Time Averages

Operations Research, 1982
In many stochastic models, particularly in queueing theory, Poisson arrivals both observe (see) a stochastic process and interact with it. In particular cases and/or under restrictive assumptions it has been shown that the fraction of arrivals that see the process in some state is equal to the fraction of time the process is in that state.

Signal arrival times

SPIE Proceedings, 2003
A femtosecond electromagnetic pulse propagating in a linear dispersive medium is analyzed in phase spaces of (space, wave number) and (time, frequency). First moment densities are computed as eigenvalues of differential operators acting on Hilbert ray representations of the pulse in relevant domains.
