论文摘要
已经显示出特殊类别的有限时间轨迹之后的观察者经历了有效的温度,即对均匀加速的观察者的Unruh温度的概括。我们考虑了这样的轨迹之后的镜子 - 因此被定位于严格的因果钻石 - 完美地反映了传入的场模式。我们发现,在镜子寿命的开始和结束时,Minkowski真空吸尘器中的惯性观察者沿半空射线检测颗粒。这些粒子分布表现出多目标纠缠,揭示了真空相关性内的新结构。相互作用是使用非扰动电路模型对其进行建模的,并且不受能量差异的困扰。
Observers following special classes of finite-lifetime trajectories have been shown to experience an effective temperature, a generalisation of the Unruh temperature for uniformly accelerated observers. We consider a mirror following such a trajectory - and is hence localised to a strictly bounded causal diamond - that perfectly reflects incoming field modes. We find that inertial observers in the Minkowski vacuum detect particles along the half null-rays at the beginning and end of the mirror's lifetime. These particle distributions exhibit multi-partite entanglement, which reveals novel structure within the vacuum correlations. The interaction is modelled using a non-perturbative circuit model and does not suffer from energy divergences.
