Title: 自旋暗能量与宇宙学巧合问题

Abstract: Recently, the so-called Elko spinor field has been proposed to be a candidate of dark energy. It is a non-standard spinor and has unusual properties. When the Elko spinor field is used in cosmology, its unusual properties could bring some interesting consequences. In the present work, we discuss the cosmological coincidence problem in the spinor dark energy models by using the dynamical system method. Our results show that the cosmological coincidence problem should be taken to heart in the investigations of spinor dark energy models. Show Chinese abstract

Abstract: 近年来，所谓的Elko旋量场被提出作为暗能量的候选者。它是一种非标准旋量，并具有异常性质。当Elko旋量场应用于宇宙学时，其异常性质可能会带来一些有趣的后果。在目前的工作中，我们利用动力系统方法讨论了旋量暗能量模型中的宇宙学巧合问题。我们的结果显示，在研究旋量暗能量模型时，应该重视宇宙学巧合问题。
