该研究通过改变相对相位追踪不同玻色子星构型和标量势下公共桥的演化，发现相对相位主要控制公共桥存续，更大相位偏移会缩短其存续时间，且该效应普遍存在。
AI 中文摘要
我们表明，在径向激发玻色子星的对撞中，相对相位主要控制公共桥的存续，而非初始形成。我们改变相对相位，追踪不同玻色子星构型和标量势下碰撞后公共桥的演化。在基准测试中，所有采样相位均形成公共桥，但更大的相位偏移会缩短其存续时间；该抑制效应在研究的所有构型和标量势中均存在。
英文摘要
We show that the relative phase primarily controls the survival, rather than the initial formation, of the common bridge in head-on collisions of radially excited boson stars. In the benchmark configuration, all sampled phases form both a common and a strong bridge. After aligning the evolutions at the same operational weak-contact level, their early post-contact evolution remains similar, while a clear phase hierarchy develops only later, with larger phase offsets producing a weaker and less persistent connection. The same suppression persists under controlled variations of the central scalar amplitude, quartic self-interaction strength, and scalar potential. These results identify relative phase as a control on the nonlinear persistence of the common bridge rather than simply on the instantaneous scalar-field overlap.
