The propagation of a free massless scalar field in a [Formula: see text]-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 asymptotically inertial, asymptotically null, and also involving a faster-than-light motion to illustrate the peculiarities of the emitted energy fluxes and quantum correlations.

虫洞创造粒子：1+1模型

自由无质量标量场在 [公式：见文本] 维 Minkowski 空间建模中的传播，考虑了虫洞。虫洞模型由两条类时轨迹组成，它们代表虫洞的入口和出口，通过一些传递函数连接，该传递函数指定到达入口的传入模式如何传递到出口。我们发现除了表示全局保形变换的传递函数外，通常会产生粒子和能量通量。我们考虑了几个例子，这些例子涉及渐近惯性、渐近为零的出口轨迹，并且还涉及比光速更快的运动，以说明发射的能量通量和量子相关性的特性。
