AI总结:

本文总结了核心坍缩超新星、双中子星并合环境中由相干或非相干作用驱动的多体集体中微子振荡现象,以及其中量子纠缠相关研究的最新进展。

摘要:

核心坍缩超新星与双中子星并合中的中微子味转换是一个复杂且尚未解决的问题,对我们理解这些环境中的动力学过程与核合成至关重要。这些环境中极高的中微子数密度会在中微子味转换过程中引发多种集体效应,其驱动机制要么是中微子-中微子相干散射,要么在某些情况下通过碰撞(非相干)相互作用实现。一群发生相互间相干散射的中微子构成一个相互作用的量子多体系统——因此,中微子之间有望产生量子纠缠,这会在它们的味演化历史中留下印记。本文旨在总结目前在理解这一现象方面取得的最新进展。

英文摘要:

Neutrino flavor transformations in core-collapse supernovae and binary neutron star mergers represent a complex and unsolved problem that is integral to our understanding of the dynamics and nucleosynthesis in these environments. The high number densities of neutrinos present in these environments can engender various collective effects in neutrino flavor transformations, driven either by neutrino-neutrino coherent scattering, or in some cases, through collisional (incoherent) interactions. An ensemble of neutrinos undergoing coherent scattering among themselves is an interacting quantum many-body system -- as such, there is a tantalising prospect of quantum entanglement developing between the neutrinos, which can leave imprints on their flavor evolution histories. Here, we seek to summarize recent progress that has been made towards understanding this phenomenon.
