摘要

时间-能量不确定性关系(TEUR)在量子力学中起着至关重要的作用,因为它允许根据理论的非常一般的原理和对称性来掌握各种现象的特殊方面。利用mandelstamm - tamm方法,最近通过将中微子能量的不确定性与振荡的特征时间尺度联系起来,推导出了中微子振荡的TEUR。有趣的是,将中微子解释为类不稳定粒子的说法被证明是在这种背景下自然出现的。后来在半经典引力理论中,通过计算一般静止弯曲时空中中微子能量不确定性的修正,以及在量子场论中,进一步讨论了这些问题,在量子场论中,可观察到的时钟被证明是与非保守的风味电荷算子相一致的。在本文中,我们对上述成果进行了综述。特别地,我们分析了TEUR的含义,并探讨了引力和非相对论效应对中微子振荡标准条件的影响。

Time–Energy Uncertainty Relation for Neutrino Oscillations: Historical Development, Applications, and Future Prospects
The time–energy uncertainty relation (TEUR) plays a fundamental role in quantum mechanics, as it allows the grasping of peculiar aspects of a variety of phenomena based on very general principles and symmetries of the theory. Using the Mandelstam–Tamm method, TEUR has recently been derived for neutrino oscillations by connecting the uncertainty in neutrino energy with the characteristic timescale of oscillations. Interestingly, the suggested interpretation of neutrinos as unstable-like particles has proved to naturally emerge in this context. Further aspects were later discussed in semiclassical gravity theory, by computing corrections to the neutrino energy uncertainty in a generic stationary curved spacetime, and in quantum field theory, where the clock observable turns out to be identified with the non-conserved flavor charge operator. In the present work, we give an overview on the above achievements. In particular, we analyze the implications of TEUR and explore the impact of gravitational and non-relativistic effects on the standard condition for neutrino oscillations.
