摘要:

本文重新研究了由自由幻影场支撑的、具有非平凡虫洞时空拓扑结构的自由复标量场形式的玻色物质模型。我们得到了一类新的带虫洞解的玻色星,其中复标量场相对于两个渐近平坦时空区域具有完全的奇宇称对称性。当虫洞喉道尺寸较小时,带虫洞玻色星的行为趋近于普通玻色星的行为;当喉道尺寸处于中等范围时,玻色星的质量和粒子数随频率变化的典型螺旋依赖关系会被环结构取代;而当喉道尺寸变得相对较大时,该环结构也会消失。特别地,在喉道尺寸趋于零的极限下,复标量场可在两个时空区域形成两个具有相反相位差的玻色星。我们分析了这类新型带虫洞玻色星的性质,并进一步阐明了虫洞的时空几何特性。

英文摘要:

In this paper, we revisit the model of bosonic matter in the form of a free complex scalar field with a nontrivial wormhole spacetime topology supported by a free phantom field. We obtain a new type of boson star with wormhole solutions, in which the complex scalar field possess full parity-odd symmetry with respect to the two asymptotically flat spacetime regions. When the size of the throat is small, The behavior of boson stars with wormhole approaches that of boson stars. When the size of the throat is intermediate, the typical spiraling dependence of the mass and the particle number on the frequency of the boson stars is replaced by a loop structure. However, as the size becomes relatively large, the loop structure will also disappear. In particular, The complex scalar field could form two boson stars with opposite phase differences with respect to the two spacetime regions in the limit of vanishing throat size. We analyze the properties of this new type of boson stars with wormhole and further show that the wormhole spacetime geometry.
