暗能量的热力学

Thermodynamics of Dark Energy

Neven Bilic

摘要:

假设暗能量是用一个自相互作用的复标量描述的,讨论了暗能量的热力学性质。我们首先表明,在一定的假设下,自相互作用复杂的标量场理论是等价的纯动力学k-本质模型。然后我们分析了k-本质的热性质,特别是我们表明,暗能量在幻影制度不一定产生负熵。

英文摘要:

Thermodynamic properties of dark energy are discussed assuming that dark energy is described in terms of a selfinteracting complex scalar. We first show that, under certain assumptions, selfinteracting complex scalar field theories are equivalent to purely kinetic k-essence models. Then we analyze the themal properties of k-essence and in particular we show that dark-energy in the phantom regime does not necessarily yield negative entropy.
