Mesoscopic electrodynamics at metal surfaces

open access: yesNanophotonics, 2021
Plasmonic phenomena in metals are commonly explored within the framework of classical electrodynamics and semiclassical models for the interactions of light with free-electron matter. The more detailed understanding of mesoscopic electrodynamics at metal

Spontaneous Emission Enhancement of CdSe Quantum Dots Embedded in a Two-dimensional Photonic Crystal L3 Nanocavity

open access: yesARO-The Scientific Journal of Koya University, 2021
Two-dimensional photonic crystal nanocavities were designed to tailor cavity quantum electrodynamics. Enhancing the spontaneous emission of low-quality factor nanocavity with embedded CdSe quantum dots (QDs) emitters is the aim of this study.

Ultimate quantum limit for amplification: a single atom in front of a mirror

open access: yesNew Journal of Physics, 2021
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional (1D) semi-infinite waveguide. We consider two setups where a drive creates population inversion in the bare or dressed basis of a

Ultrafast nonlocal control of spontaneous emission [PDF]

open access: yes, 2013
Solid-state cavity quantum electrodynamics systems will form scalable nodes of future quantum networks, allowing the storage, processing and retrieval of quantum bits, where a real-time control of the radiative interaction in the cavity is required to ...

Quantum Hall phases emerging from atom–photon interactions

open access: yesnpj 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

open access: yesTheoria, 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.

Quantum electrodynamical metamaterials

open access: yesPhysical 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 ...

Atomic-waveguide quantum electrodynamics

open access: yesPhysical 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.

Does Quantum Electrodynamics Have an Arrow of Time? [PDF]

open access: yes, 2005
Quantum electrodynamics is a time-symmetric theory that is part of the electroweak interaction, which is invariant under a generalized form of this symmetry, the PCT transformation.
