“…However, a collection of later papers by Shirokov [2] and others [3][4][5] argued against this solution and attributed the causal result to an approximation that removed the lower bound on photon frequencies. Although some authors agree that Fermi's solution is valid in some regards [6][7][8], there remain interesting questions surrounding the a-causal nature of correlations between the two atoms that continue to be a topic of study and debate [9].…”

In a recent paper [Southall et al., Locally-acting mirror Hamiltonians, arXiv:1908.07597 (2021], we showed that it is possible to design locally-acting mirror Hamiltonians which only affect incoming but do not change the dynamics of outgoing wave packets. To better justify our approach, this paper presents a systematic quantisation of the electromagnetic field in position space. Starting from the assumption that the basic building blocks of the electromagnetic field in one dimension are localised bosonic wave packets with a clear direction of propagation-so-called bosons localised in position (BLiPs)-we identify the relevant Schrödinger equation and construct Lorentz covariant electric and magnetic field observables. Our description contains the standard description of the quantised electromagnetic field which is shown to apply to a subspace of states.

We revisit the Fermi two-atoms problem in the framework of disordered systems. In our model we consider a two-qubits system linearly coupled with a quantum massless scalar field. We analyze the energy transfer between the qubits under different experimental perspectives. In addition, we assume that the coefficients of the Klein-Gordon equation are random functions of the spatial coordinates. The disordered medium is modeled by a centered, stationary and Gaussian process. We demonstrate that the classical notion of causality emerges only in the wave zone in the presence of random fluctuations of the light cone. Possible repercussions are discussed.
