A physically-motivated gauge-independent quantisation of the electromagnetic field on curved spacetimes. (arXiv:1811.09594v1 [quant-ph])

Recently, Bennett et al. [Eur. J. Phys. 37:014001, 2016] presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space. In this paper, we generalise this scheme to curved spacetimes to gain more insight into relativistic quantum optics. Working within the standard assumptions of quantum field theory and assuming wave-particle duality, we obtain the Hamiltonian, H, and the electric and magnetic field observables, E and B, without having to invoke a specific gauge. As an example, we quantise the electromagnetic field in the spacetime of an accelerated Minkowski observer, the Rindler space, and demonstrate consistency with other field quantisation schemes by reproducing the Unruh effect.
