作为暗能量和暗物质的量子残余

Quantum Remnant as Dark Energy and Dark Matter

Sang Pyo Kim, Seoktae Koh

摘要:

研究了在不确定原理保护下标量场的量子剩余。在宇宙演化后期幸存下来的量子残余可能会提供暗能量和暗物质,这取决于势能。虽然量子余项具有复标量场(自旋间隔)暗能量模型的一些有用的性质,但尽管它避免了Q球的形成,但量子涨落对$q<1$和$V \sim ϕ^q$的线性微扰仍然是不稳定的。

英文摘要:

We study the quantum remnant of a scalar field protected by the uncertainty principle. The quantum remnant that survived the later stage of evolution of the universe may provide dark energy and dark matter depending on the potential. Though the quantum remnant shares some useful property of complex scalar field (spintessence) dark energy model, % However although it avoids the formation of Q-ball, quantum fluctuations are still unstable to the linear perturbations for $V \sim ϕ^q$ with $q<1$ as in the spintessence model.
