Arrival time from the general theory of quantum time distributions

Ambiguities of arrival-time distributions in quantum theory

We consider the definition that might be given to the time at which a particle arrives at a given place, both in standard quantum theory and also in Bohmian mechanics. We discuss an ambiguity that arises in the standard theory in three, but not in one, spatial dimension. 1 Participating Guest, Lawrence Berkeley National Laboratory e-mail: [email protected]

Arrival Time in Quantum Mechanics

Time-of-arrival probabilities and quantum measurements

We study the construction of probability densities for time-of-arrival in quantum mechanics. Our treatment is based upon the facts that (i) time appears in quantum theory as an external parameter to the system, and (ii) propositions about the time-of-arrival appear naturally when one considers histories. The definition of time-of-arrival probabilities is straightforward in stochastic processes....

Time of arrival in quantum mechanics.

We study the problem of computing the probability for the time-of-arrival of a quantum particle at a given spatial position. We consider a solution to this problem based on the spectral decomposition of the particle's (Heisenberg) state into the eigenstates of a suitable operator, which we denote as the \time-of-arrival" operator. We discuss the general properties of this operator. We construct...
