Time-of-arrival distributions from position-momentum and energy-time joint measurements
A. D. Baute, I. L. Egusquiza, J. G. Muga +1
The position-momentum quasi-distribution obtained from an Arthurs and Kelly joint measurement model is used to obtain indirectly an ``operational'' time-of-arrival (TOA) distributi…
Free motion time-of-arrival operator and probability distribution
I. L. Egusquiza, J. G. Muga
We reappraise and clarify the contradictory statements found in the literature concerning the time-of-arrival operator introduced by Aharonov and Bohm in Phys. Rev. {\bf 122}, 1649…
Time-of-arrival distribution for arbitrary potentials and Wigner's time-energy uncertainty relation
A. D Baute, R. Sala Mayato, J. P. Palao +2
A realization of the concept of "crossing state" invoked, but not implemented, by Wigner, allows to advance in two important aspects of the time of arrival in quantum mechanics: (i…
Average local values and local variances in quantum mechanics
J. G. Muga, J. P. Palao, R. Sala
Several definitions for the average local value and local variance of a quantum observable are examined and compared with their classical counterparts. An explicit way to construct…
Barrier traversal times using a phenomenological track formation model
J. P. Palao, J. G. Muga, S. Brouard +1
A phenomenological model for a measurement of barrier traversal times for particles is proposed. Two idealized detectors for passage and arrival provide entrance and exit times for…
