论文摘要
在本文中,我们研究了在Schwarzschild公制中传播的两个风味中微子的量子相干性。实际上,通过计算Leggett-Garg不平等(LGI)的参数$ k_ {3} $来定性地探索此问题,也可以通过评估$ l_ {1} $ - norm,$ {\ cal c}(ρ)$进行定量。使用弱场近似值,我们表明重力效应在某些能量间隔中降低了$ k_ {3} $的最大值,以至于没有违规的方式,虽然它留下了最大量子相干性,但$ {\ cal c}(\ cal c}(ρ)$不变。
In this paper, we investigate the quantum coherence for two flavor neutrinos propagating in a Schwarzschild metric. In fact, this issue is explored both qualitatively via calculating the parameter $K_{3}$ in Leggett-Garg inequality (LGI) and also quantitatively by evaluating the $l_{1}$-norm, ${\cal C}(ρ)$. Using the weak field approximations, we show that the gravitational effects decrease the maximum value of $K_{3}$ for some intervals of energy such a way that there is no violation, while it leaves the maximum amount of the quantum coherence, ${\cal C}(ρ)$ unchanged.
