Quantum electrodynamical metamaterials
Physical Review A, 2023 Recent experiments have revealed ultrastrong coupling between light and matter as a promising avenue for modifying material properties, such as electrical transport, chemical reaction rates, and even superconductivity. Here, we explore (ultra)strong coupling as a means for manipulating the optical response of metamaterials based on ensembles of ...

Quantum Hall phases emerging from atom–photon interactions
npj Quantum Information, 2021 We reveal the emergence of quantum Hall phases, topological edge states, spectral Landau levels, and Hofstadter butterfly spectra in the two-particle Hilbert space of an array of periodically spaced two-level atoms coupled to a waveguide (waveguide ...

The Relation between Classical and Quantum Electrodynamics
Theoria, 2011 Quantum electrodynamics presents intrinsic limitations in the description of physical processes that make it impossible to recover from it the type of description we have in classical electrodynamics.

Atomic-waveguide quantum electrodynamics
Physical Review Research, 2020 Atom arrays are a new type of quantum light-matter interface. Here we propose to employ one-dimensional ordered arrays as atomic waveguides. These arrays support optical guided modes that do not decay into free space.

Quasiperiodic circuit quantum electrodynamics
npj Quantum Information, 2023 Superconducting circuits are an extremely versatile platform to realize quantum information hardware and to emulate topological materials. We here show how a simple arrangement of capacitors and conventional superconductor-insulator-superconductor ...

Visualizing the emission of a single photon with frequency and time resolved spectroscopy [PDF]
Quantum, 2021 At the dawn of Quantum Physics, Wigner and Weisskopf obtained a full analytical description (a $\textit{photon portrait}$) of the emission of a single photon by a two-level system, using the basis of frequency modes (Weisskopf and Wigner, "Zeitschrift ...

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.

Quantum electrodynamics in finite volume and nonrelativistic effective field theories
Physics Letters B, 2016 Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativistic
