• Abstract: We present a covariant framework for the quantization of the electromagnetic field in the presence of magnetic monopoles. Building on the two-potential formalism of Cabibbo and Ferrari, which treats electric and magnetic sources on equal footing and reveals a $U(1) \times U(1)$ gauge symmetry, we extend the theory into the quantum domain. Using the Gupta-Bleuler procedure in the Feynman-'t Hooft gauge, we construct the physical Hilbert space and eliminate negative-norm states. The resulting theory predicts, in addition to conventional photons, the existence of dual photons associated with magnetic charges. We discuss the role of these dual excitations and their possible relevance in the broader context of electromagnetic duality and gauge theories.

  We consider the problem of magnetic charges in $(2+1)$ dimensions for a torus geometry in real-space. We compute the Hall conductivity associated with transport of these charges for the case of negligible gapless excitations. We find it is proportional to an integer-valued topological invariant $mathcalQ$, corresponding to a magnetic quantum Hall effect.

• A theory of local photons with applications in quantum field theory [0.0]
  In quantum optics it is usual to describe the basic energy quanta of the electromagnetic (EM) field, photons, in terms of monochromatic waves. We take an alternative approach and quantise the free EM field in both one and three dimensions in terms of quanta that are perfectly localised. Here we show that, unlike standard quantisation schemes, our approach predicts the causal propagation of localised photonic wave packets.

  Quantum simulation of lattice gauge theories (LGTs) aims at tackling non-perturbative particle and condensed matter physics. One of the current challenges is to go beyond 1+1 dimensions, where four-body (plaquette) interactions, not contained naturally in quantum simulating devices, appear. We show how to prepare the ground state and measure Wilson loops using state-of-the-art techniques in atomic physics.
