论文摘要
Ellis-Bronnikov解决方案为研究虫洞物理学各个方面的研究提供了一个简单的玩具模型。在这项工作中，我们在此背景下求解了klein-gordon方程，并根据HEUN的功能找到了精确的解决方案。这可以描述“标量云”（$，即$本地化的粒子状配置）或标量波。但是，在前一种情况下，标量场的径向衍生物在虫洞的喉咙（球形案例除外）是不连续的。对于适当的标量场自我交织，这种病理是不存在的，我们为在Ellis-Bronnikov蠕虫背景中存在球形对称和旋转的Q-balls提供了证据。
The Ellis-Bronnikov solution provides a simple toy model for the study of various aspects of wormhole physics. In this work we solve the Klein-Gordon equation in this background and find an exact solution in terms of Heun's function. This may describe 'scalar clouds' ($i.e.$ localized, particle-like configuration) or scalar waves. However, in the former case, the radial derivative of the scalar field is discontinuous at the wormhole's throat (except for the spherical case). This pathology is absent for a suitable scalar field self-interaction, and we provide evidence for the existence of spherically symmetric and spinning Q-balls in a Ellis-Bronnikov wormhole background.
