熵力情形下一个禁止暴胀的不可行定理
A No-go Theorem Prohibiting Inflation in the Entropic Force Scenario
摘要:
我们证明了在Verlinde的熵力方案中为了适应暴胀,需要在全息屏上引入负温度,这将引入能量不守恒等几个难题。如果试图修改爱因斯坦方程的推导以避免负温度,我们证明了不可能找到一个合适的新的温度定义来推导爱因斯坦方程。
英文摘要:
We show that to accommodate inflation in the entropic force scenario of Verlinde, it is necessary to introduce a negative temperature on a holographic screen, this will introduce several puzzles such as energy non-conservation. If one tries to modify the derivation of the Einstein equations to avoid a negative temperature, we prove that it is impossible to find a proper new definition of temperature to derive the Einstein equations.
