静态虫洞时空中量子化质量场的应力-能量张量

Stress-energy tensor of quantized massive fields in static wormhole spacetimes

摘要:

为了能够穿越,静态洛伦兹虫洞必须由一些违反弱能量条件的奇异物质构成。量子化场是自然的候选者,因为它们的应力-能量张量在许多情况下具有所需的性质。本文构造并研究了六个静态虫洞时空中量子化质量标量场、旋量场和矢量场的应力能量张量。我们发现,在所有考虑的情况下,量子场违反莫里斯-索恩条件,并没有必要的形式,以支持虫洞喉。这与先前的结果一致,并表明大质量量子场使虫洞的可操作性降低。

英文摘要:

In order to be traversable, the static Lorentzian wormhole must be made out of some exotic matter that violates the weak energy condition. The quantized fields are the natural candidates as their stress-energy tensor, in many cases, possesses desired properties. In this paper we construct and examine the stress-energy tensor of the quantized massive scalar, spinor and vector fields in six static wormhole spacetimes. We find that in all considered cases the quantum fields violate the Morris-Thorne conditions and do not have the form necessary to support the wormhole throat. This is in concord with the previous results and indicates that the massive quantum fields make the wormholes less operable.
