热视界中的宇宙能量与第一定律

Cosmological energy in a thermo-horizon and the first law

Cécile Barbachoux, Jérome Gariel, Gérard Le Denmat

摘要:

我们考虑一个宇宙视界,命名为热视界,它与温度和贝肯斯坦-霍金熵相关联,并且服从通过相应极限面计算的能量流的第一定律。我们指出第一定律和视界内总能量的定义之间的矛盾。当第一定律被与事件视界相关的类真空分量的吉布斯方程所取代时,这种矛盾就消除了。

英文摘要:

We consider a cosmological horizon, named thermo-horizon, to which are associated a temperature and an entropy of Bekenstein-Hawking and which obeys the first law for an energy flow calculated through the corresponding limit surface. We point out a contradiction between the first law and the definition of the total energy contained inside the horizon. This contradiction is removed when the first law is replaced by a Gibbs' equation for a vacuum-like component associated to the event horizon.
