Morris-Thorne虫洞中奇异物质的性质

On the nature of exotic matter in Morris-Thorne wormholes

Peter K. F. Kuhfittig

摘要:

众所周知,由状态方程$p=ωρ$,$ω<-1$表征的幻象能量可以支持Morris-Thorne虫洞,因为它导致违反零能量条件。本文的目的是证明,在下列意义下,逆命题也成立:对于一个典型的形函数,喉道附近奇异物质的状态方程由$p_r=ωρ$,$ω<-1$给出,其中$p_r$是径向压力。其中的一些影响也被认为是。

英文摘要:

It is well known that phantom energy, which is characterized by the equation of state $p=ωρ$, $ω<-1$, can support Morris-Thorne wormholes since it leads to a violation of the null energy condition. The purpose of this note is to show that the converse is also true in the following sense: for a typical shape function, the equation of state of exotic matter in the vicinity of the throat is given by $p_r=ωρ$, $ω<-1$, where $p_r$ is the radial pressure. Some implications thereof are also considered.
