摘要：

We generalize 1 + 1-dimensional formalism derived by Ahmadi et al. [Phys. Rev. D 93, 124031 (2016)] to investigate an effect of relativistic acceleration on localized two-mode Gaussian quantum states in 3 + 1-dimensional spacetime. The following framework is then used to analyze entanglement of the Minkowski vacuum as witnessed by two accelerating observers that move either collinearly or noncollinearly.
