Quantum Electrodynamics vacuum polarization solver

open access: yesNew Journal of Physics, 2021
The self-consistent modeling of vacuum polarization due to virtual electron-positron fluctuations is of relevance for many near term experiments associated with high intensity radiation sources and represents a milestone in describing scenarios of ...

Detection of Hybrid Optical Anapoles in Dielectric Microspheres

open access: yesAdvanced Optical Materials, EarlyView.
In this work, hybrid optical anapoles are detected in dielectric microspehers using dual detection optical spectroscopy. The results show that the excitation of TiO2 microspheres under tightly focused Gaussian Beam illumination leads to the appearence of scattering minima in both the forward and backward directions within specific wavelength ranges ...

Nonequilibrium quantum electrodynamics [PDF]

open access: yesPhysical Review D, 1998
We employ the influence functional technique to trace out the photonic contribution from full quantum electrodynamics. The reduced density matrix propagator for the spinor field is then constructed. We discuss the role of time-dependent renormalization in the propagator and focus on the possibility of obtaining dynamically induced superselection rules.

Strong coupling of a single photon to a superconducting qubit using circuit quantum electrodynamics [PDF]

open access: yesNature, 2004
The interaction of matter and light is one of the fundamental processes occurring in nature, and its most elementary form is realized when a single atom interacts with a single photon.

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective

open access: yesAdvanced Photonics Research, EarlyView.
This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Interpolating Quantum Electrodynamics [PDF]

open access: yesFew-Body Systems, 2018
We discuss the interpolation between the instant form dynamics (IFD) and the light-front dynamics (LFD) proposed by Dirac in 1949 and present its application to quantum electrodynamics (QED). Our analysis clarifies any conceivable confusion in the prevailing notion of the equivalence between the IFD at infinite momentum frame and the LFD. Entwining the

Quantum-Optical Spectrometry in Relativistic Laser–Plasma Interactions Using the High-Harmonic Generation Process: A Proposal

open access: yesPhotonics, 2021
Quantum-optical spectrometry is a recently developed shot-to-shot photon correlation-based method, namely using a quantum spectrometer (QS), that has been used to reveal the quantum optical nature of intense laser–matter interactions and connect the ...

Topological phase transitions in the non-Abelian honeycomb lattice

open access: yes, 2010
Ultracold Fermi gases trapped in honeycomb optical lattices provide an intriguing scenario, where relativistic quantum electrodynamics can be tested. Here, we generalize this system to non-Abelian quantum electrodynamics, where massless Dirac fermions ...

Two-Dimensional Quantum-Link Lattice Quantum Electrodynamics at Finite Density [PDF]

open access: yesPhysical Review X, 2019
We present a tree tensor network approach to the study of lattice gauge theories in two spatial dimensions showing how to perform numerical simulations of theories in presence of fermionic matter and four-body magnetic terms, at zero and finite density ...

Generation of High‐Brilliance Polarized γ‐Rays Via Vacuum Dichroism‐Assisted Vacuum Birefringence

open access: yesAdvanced Science, EarlyView.
A novel method is proposed for generating such γ‐photon beams via the vacuum‐dichroism‐assisted quantum vacuum birefringence effect, only utilizing well‐established unpolarized electron beams and solving the critical problem of demanding polarized ones.
