论文摘要
我们考虑了最近出现在文献中的两种必要和充分的条件，分别被称为无信号和箭头条件，并在中微子风味过渡的背景下研究了它们，在平面波描述和波浪包装方法中。然后，我们将上述研究的结果与garg不平等的各种表述的含义进行了比较。特别是，我们表明，在中微子振荡中实现了大分子主义的解决条件意味着达到了leggett-garg不平等的实现，而相反的情况并非如此。最后，在波数据包方法的框架中，我们还证明，对于距离长度长的距离，无信号的条件总是违反，而加尔格的不平等不平等。
We consider two necessary and sufficient conditions for macrorealism recently appeared in the literature, known as no-signaling-in-time and arrow-of-time conditions, respectively, and study them in the context of neutrino flavor transitions, within both the plane wave description and the wave packet approach. We then compare the outcome of the above investigation with the implication of various formulations of Leggett--Garg inequalities. In particular, we show that the fulfillment of the addressed conditions for macrorealism in neutrino oscillations implies the fulfillment of Leggett--Garg inequalities, whereas the converse is not true. Finally, in the framework of wave packet approach, we also prove that, for distances longer than the coherence length, the no-signaling-in-time condition is always violated whilst Leggett--Garg inequalities are not.
