Quantum fields in accelerated cavities: from relativistic velocities to a desktop experiment

We address quantum fields in an accelerated cavity in (3+1)-dimensional Minkowski spacetime in a perturbative formalism that assumes acceleration to remain small but allows the velocities, travel times and travel distances to be arbitrary, and remains in particular valid when the velocities become relativistic. The formalism is well suited for analysing acceleration effects on quantum information protocols, and it generalises to analogue systems that simulate mechanical cavity motion. As an application, we identify a desktop experimental scenario where mode mixing within the cavity appears to be at the threshold of current technology. (Based on D. E. Bruschi, J. Louko, D. Faccio and I. Fuentes, New J. Phys. 15 (2013) 073052 [arXiv:1210.6772].)
