Coupling quantum emitters in metal–insulator–metal heterostructure: Green tensor approach in the quasi-static limit

open access: yesAIP Advances, 2022
Coupling between quantum emitters (QEs) has been a topic extensively explored in recent years. Theoretical models based on the Lindblad master equation and mapping to cascaded quantum system has shed light to the chiral coupling phenomena from the aspect

The quantum scale invariance in graphene-like quantum electrodynamics

open access: yesPhysics Letters B, 2022
The ultraviolet and infrared finiteness of a parity-even massless planar quantum electrodynamics mimics the scale invariance in graphene.

Variational quantum electrodynamics [PDF]

open access: yesPhysical Review D, 2014
A variational method is discussed, based on the principle of minimal variance. The method seems to be suited for gauge interacting fermions, and the simple case of quantum electrodynamics is discussed in detail. The issue of renormalization is addressed, and the renormalized propagators are shown to be the solution of a set of finite integral equations.

Run-away solutions in relativistic spin 1/2 quantum electrodynamics [PDF]

open access: yes, 1997
The existence of run-away solutions in classical and non-relativistic quantum electrodynamics is reviewed. It is shown that the less singular high energy behavior of relativistic spin 1/2 quantum electrodynamics precludes an analogous behavior in that ...

The Importance of Boundary Conditions in Quantum Mechanics [PDF]

open access: yes, 2003
We discuss the role of boundary conditions in determining the physical content of the solutions of the Schrodinger equation. We study the standing-wave, the ``in,'' the ``out,'' and the purely outgoing boundary conditions. As well, we rephrase Feynman's $

On Quantum Corrections to Chern-Simons Spinor Electrodynamics [PDF]

open access: yes, 1997
We make a detailed investigation on the quantum corrections to Chern-Simons spinor electrodynamics. Starting from Chern-Simons spinor quantum electrodynamics with the Maxwell term $-1/(4\gamma){\int}d^3x F_{\mu\nu}F^{\mu\nu}$ and by calculating the ...

Polaritonics: from microcavities to sub-wavelength confinement

open access: yesNanophotonics, 2019
Following the initial success of cavity quantum electrodynamics in atomic systems, strong coupling between light and matter excitations is now achieved in several solid-state set-ups.

Quantum electrodynamics with anisotropic scaling: Heisenberg-Euler action and Schwinger pair production in the bilayer graphene [PDF]

open access: yes, 2012
We discuss quantum electrodynamics emerging in the vacua with anisotropic scaling. Systems with anisotropic scaling were suggested by Horava in relation to the quantum theory of gravity.

Quantum Electrodynamics at Large Distances II: Nature of the Dominant Singularities

open access: yes, 1995
Accurate calculations of macroscopic and mesoscopic properties in quantum electrodynamics require careful treatment of infrared divergences: standard treatments introduce spurious large-distances effects.
