论文摘要
纠缠系统中的非本地相关性通常会被贝尔违反不平等的措施捕获。最近显示，与贝尔的不平等违规相比，在中微子系统中，量子相干性（NAQC）的非本地优势的度量可以被认为是对非本地相关性的更强度量。在这项工作中，我们在两种风味中微子振荡的背景下分析了非标准相互作用（NSI）对沙丘，Minos，T2K，Kamland，Kamland，Juno和Daya Bay实验设置的影响。我们发现，即使在NSI的存在下，贝尔的不平等违规也发生在整个能量范围内，而只有在某些特定的能量范围内观察到NAQC违规，这证明了NAQC的更基本特征。此外，我们发现NSI可以在给定的实验设置的较高能量范围内增强NAQC和Bell的不平等参数的侵犯。这些增强功能是Kamland实验的最大值。但是，违反标准模型预测的贝尔不平等参数的可能提高可能高达11％，而对于NAQC，可能是7％。因此，尽管NAQC是非经典性的相对较强的见证，但与贝尔的不平等参数相比，它对NSI效应的敏感性较小。
Non-local correlations in entangled systems are usually captured by measures such as Bell's inequality violation. It was recently shown that in neutrino systems, a measure of non-local advantage of quantum coherence (NAQC) can be considered as a stronger measure of non-local correlations as compared to the Bell's inequality violation. In this work, we analyze the effects of non standard interaction (NSI) on these measures in the context of two flavour neutrino oscillations for DUNE, MINOS, T2K, KamLAND, JUNO and Daya Bay experimental set-ups. We find that even in the presence of NSI, Bell's inequality violation occurs in the entire energy range whereas the NAQC violation is observed only in some specific energy range justifying the more elementary feature of NAQC. Further, we find that NSI can enhance the violation of NAQC and Bell's inequality parameter in the higher energy range of a given experimental set-up; these enhancements being maximal for the KamLAND experiment. However, the possible enhancement in the violation of the Bell's inequality parameter over the standard model prediction can be up to 11% whereas for NAQC it is 7%. Thus although NAQC is a comparatively stronger witness of nonclassicality, it shows lesser sensitivity to NSI effects in comparison to the Bell's inequality parameter.
