没有小参数的小暗能量

Small dark energy without small parameters

Benjamin Shlaer

摘要:

我们提出了一个原型模型,解决了宇宙学常数问题,仅使用物质,即,而不改变重力。它的一般宇宙学解将任意大的负暗能量调整为由初始场速度参数抑制的正值。暴胀初始条件导致正暗能量的量级比任何模型参数或初始条件下的任何尺度都呈指数级小。

英文摘要:

We present a prototype model that resolves the cosmological constant problem using matter alone, i.e., without modifying gravity. Its generic cosmological solutions adjust an arbitrarily large, negative dark energy to a positive value parametrically suppressed by an initial field velocity. Inflationary initial conditions lead to a positive dark energy exponentially smaller in magnitude than any model parameter, or any scale in the initial conditions.
