论文摘要
研究了基于Barton-Calogeracos（BC）动作的相对论，半透明镜在1+3D Minkowski时期生产标量颗粒。相应的Bogoliubov系数是针对具有任意轨迹的镜像得出的。特别是，我们将派生公式应用于重力塌陷轨迹。此外，我们确定了粒子谱与粒子产生概率之间的关系，并证明了我们的方法与文献中现有方法之间的等效性，该方法仅限于1+1D。简而言之，我们的治疗将研究扩展到1+3D时空。最后，我们提供了第三种使用S-Matrix形式主义查找粒子谱的方法。
Production of scalar particles by a relativistic, semi-transparent mirror in 1+3D Minkowski spacetime based on the Barton-Calogeracos (BC) action is investigated. The corresponding Bogoliubov coefficients are derived for a mirror with arbitrary trajectory. In particular, we apply our derived formula to the gravitational collapse trajectory. In addition, we identify the relation between the particle spectrum and the particle production probability, and we demonstrate the equivalence between our approach and the existing approach in the literature, which is restricted to 1+1D. In short, our treatment extends the study to 1+3D spacetime. Lastly, we offer a third approach for finding the particle spectrum using the S-matrix formalism.
