论文摘要
考虑了1 + 1维的Minkowski空间建模虫洞中的自由无质量标量场的传播。虫洞模型由两个时间型轨迹组成，这些轨迹代表虫洞的入口和出口，该虫孔的出口是通过某些传输函数连接的，这些函数指定进入入口的传入模式如何转移到出口。我们发现，除了代表全局综合转换的传递函数外，颗粒和能通量是普遍产生的。我们考虑了几个涉及出口轨迹的示例，这些示例是惯性，渐近无效的，并且还涉及更快的运动，以说明发射能量通量和量子相关性的特殊性。
The propagation of a free massless scalar field in a 1 + 1 dimensional Minkowski space modeling a wormhole is considered. The wormhole model consists on two timelike trajectories, which represent the entrance and the exit of the wormhole, connected via some transfer function that specifies how incoming modes that reach the entrance are transferred to the exit. We find that particles and energy fluxes are generically produced except for transfer functions that represent global conformal transformations. We consider several examples involving exit trajectories which are assymptotically inertial, asymptotically null and also involving a faster-than-light motion to illustrate the peculiarities of the emitted energy fluxes and quantum correlations.
