Symmetries in non-relativistic quantum electrodynamics [PDF]

open access: yesReviews in Mathematical Physics, Vol. 35 No. 8 (2023), 2023
We define symmetries in non-relativistic quantum electrodynamics, which have the physical interpretation of rotation, parity and time reversal symmetry. We collect transformation properties related to these symmetries in Fock space representation as well as in the Schr\"odinger representation. As an application, we generalize and improve theorems about

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.

Quasiperiodic circuit quantum electrodynamics

open access: yesnpj 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 ...

PT-Symmetric Quantum Electrodynamics [PDF]

open access: yes, 2005
The Hamiltonian for quantum electrodynamics becomes non-Hermitian if the unrenormalized electric charge $e$ is taken to be imaginary. However, if one also specifies that the potential $A^\mu$ in such a theory transforms as a pseudovector rather than a ...

Cavity-Enhanced Two-Photon Interference using Remote Quantum Dot Sources [PDF]

open access: yes, 2015
Quantum dots in cavities have been shown to be very bright sources of indistinguishable single photons. Yet the quantum interference between two bright quantum dot sources, a critical step for photon based quantum computation, has never been investigated.

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.

Mark Burgin’s Contribution to the Foundation of Mathematics

open access: yesPhilosophies, 2023
In this paper, I attempt to describe Mark Burgin’s results in non-Diophantine mathematics, which are important for the foundation of mathematics and its application in quantum field theory.

Quantum theory of an electromagnetic observer: classically behaving macroscopic systems and emergence of classical world in quantum electrodynamics [PDF]

open access: yesPhys Rev A92, 022122 (2015), 2015
Quantum electrodynamics under conditions of distinguishability of interacting matter entities, and of controlled actions and back-actions between them, is considered. Such "mesoscopic quantum electrodynamics" is shown to share its dynamical structure with the classical stochastic electrodynamics.

Quantum bath engineering of a high impedance microwave mode through quasiparticle tunneling

open access: yesNature Communications, 2022
Quantum bath engineering in the context of circuit quantum electrodynamics typically relies on single-photon losses. Aiello et al. demonstrate an approach for engineering higher-order photon losses in a microwave resonator coupled to a tunnel junction ...
