论文摘要
作为IceCube或Super-Kamiokande的实验已成功地检测到高能中的中微子。从理论上预测了超低能量范围内的中微子（$ \ MATHCAL {E} <1.0〜 \ rm {EV} $），但它们的观察仍然难以捉摸，并且没有为该工作提出任何具体的实验方案。在这里，我们提出了一种基于石墨烯等离子超材料的新型方案，以检测超低的能量中微子。我们声称，与固态等离子体相互作用的缓慢中微子通量由于中微子 - 中微子 - 种植体的相互作用而与固态等离子体相互作用，这使人联想到天体物理学和实验室等离子体中的束气值不稳定。我们利用弱相互作用的半古典极限来描述石墨烯中中微子和电子之间的耦合。为了实现该方案，我们研究了石墨烯超材料中产生的中微子 - 血浆不稳定性，该质量由石墨烯层的周期性堆叠组成。我们的发现表明，这种石墨烯超材料中血浆波的受控激发允许在能量范围内检测中微子$ \ sim 1.0〜 \ rm {μev} -100〜 \ rm {mev} $，而范围为$ 10^{4} {4} -10^{4} -10^{10} \ rmmm s^{ - 1}} $。
Experiments as IceCube or Super-Kamiokande have been successful in detecting highly energetic neutrinos in the. Neutrinos in the ultra-low energy range ($\mathcal{E}<1.0~\rm{eV}$) have been theoretically predicted but their observation remain elusive, and no concrete experimental scheme has been proposed for that job. Here, we propose a novel scheme based on graphene plasmonic metamaterials to designed to detect ultra-low energetic neutrinos. We claim that slow neutrino fluxes, interacting with solid-state plasmas, can generate an instability due to the weak neutrino-plasmon interaction, which is reminiscent of the beam-plasma instability taking place in astrophysics and laboratory plasmas. We make use of the semi-classical limit of the weak interaction to describe the coupling between the neutrinos and electrons in graphene. To render the scheme practical, we investigate the neutrino-plasma instability produced in a graphene metamaterial, composed by a periodic stacking of graphene layers. Our findings reveal that the controlled excitation of plasma waves in such graphene metamaterial allows for the detection of neutrinos in the energy range $\sim 1.0~\rm{μeV}-100~\rm{meV}$, and fluxes in the range $10^{4}-10^{10} \rm{cm^{-2} s^{-1}}$.
