Braided quantum electrodynamics
Journal of High Energy Physics, 2023 The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

Quantum Electrodynamics in a Topological Waveguide [PDF]
Physical Review X, 2020 While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic bath itself.

Circuit quantum electrodynamics of granular aluminum resonators. [PDF]
Nat Commun, 2018 Granular aluminum (grAl) is a promising high kinetic inductance material for detectors, amplifiers, and qubits. Here we model the grAl structure, consisting of pure aluminum grains separated by thin aluminum oxide barriers, as a network of Josephson ...

Magnetic field compatible circuit quantum electrodynamics with graphene Josephson junctions. [PDF]
Nat Commun, 2018 Circuit quantum electrodynamics has proven to be a powerful tool to probe mesoscopic effects in hybrid systems and is used in several quantum computing (QC) proposals that require a transmon qubit able to operate in strong magnetic fields.

On the Renormalization in Quantum Electrodynamics [PDF]
Progress of Theoretical Physics, 1952 The new renonnalization procedure in quantum electrodynamics is presented in this paper. With this procedure, the finite S-matrix can be automatically obtained by· use of the modified commutation relations and propagation functions and, therefore, without introducing the counter tenns of mass- and charge-types.

Phenomenological Quantum-Electrodynamics
Physical Review, 1948 The quantization of the pure radiation field in a uniformly moving refractive medium is carried through both in the Hamiltonian and in the symmetrical four-dimensional form. The total energy and momentum are diagonalized. For a medium velocity larger than $\frac{c}{n}$ there occur photons with negative energy.

Resolution of superluminal signalling in non-perturbative cavity quantum electrodynamics [PDF]
Nature Communications, 2018 Quantum Rabi model is a standard tool for describing cavity quantum electrodynamics, but the potential shortcomings of its single-mode version are usually neglected.

On-demand directional microwave photon emission using waveguide quantum electrodynamics [PDF]
Nature Physics, 2022 Routing quantum information between non-local computational nodes is a foundation for extensible networks of quantum processors. Quantum information transfer between arbitrary nodes is generally mediated either by photons that propagate between them or ...
