任意势流的到达时间分布和Wigner的时能测不准关系

Time-of-arrival distribution for arbitrary potentials and Wigner's time-energy uncertainty relation

A. D Baute, R. Sala Mayato, J. P. Palao, J. G. Muga, I. L. Egusquiza

摘要:

由维格纳提出但未实现的“交叉态”概念的实现,允许在量子力学中的到达时间的两个重要方面取得进展:(i)对于自由运动,我们发现Aharonov等人在Phys.Rev.A57中描述的限制,4130(1998)中关于某些测量模型在低能量下的到达时间不确定性的理论事实上已经存在于Kijowski的本征到达时间分布中;(ii)我们还发现了这个分布对于任意势和位置的协变推广。

英文摘要:

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) For free motion, we find that the limitations described by Aharonov et al. in Phys. Rev. A 57, 4130 (1998) for the time-of-arrival uncertainty at low energies for certain mesurement models are in fact already present in the intrinsic time-of-arrival distribution of Kijowski; (ii) We have also found a covariant generalization of this distribution for arbitrary potentials and positions.
