摘要
本文研究了量子无质量Klein Gordon (KG)标量场Coleman Weinberg自相互作用势对具有可穿越虫洞拓扑结构的最小耦合Janis-Newman-Winicour (JNW)球对称静态弯曲时空摄动的影响。这样,我们通过WKB近似计算出相应的霍金温度、粒子产生率、辐射能量密度、光度、粒子吸收因子、质量损失和透射概率。本文是参考文献部分最近发表的研究成果的延伸,在参考文献中,我们研究了具有奇异裸拓扑的JNW时空中自由大质量KG量子波的效应,以找到与上述相同的量。事实上,JNW时空具有实标量电荷的奇异裸态,但具有虚标量电荷的可穿越虫洞拓扑。
Coleman Weinberg potential and creation of boson particles at the JNW wormhole spacetime
This work is dedicated to investigate effects of the Coleman Weinberg self-interaction potential of quantum massless Klein Gordon (KG) scalar fields on perturbation of a minimally coupled Janis–Newman–Winicour (JNW) spherically symmetric static curved spacetime with traversable wormhole topology. In this way, we calculate the corresponding Hawking temperature, rate of particles production, radiation energy density, luminosity, particle absorption factor, mass loss and transmission probability via WKB approximation. This work is extension of the recently published work addressed in the reference section, in which we studied effects of free massive KG quantum waves to find same quantities above for the JNW spacetime with singular naked topology. In fact the JNW spacetime has singular naked with real scalar charge but is traversable wormhole topology with imaginary scalar charge.
