An explanation for the muon and electron g − 2 anomalies and dark matter

Journal of High Energy Physics, 2020
We propose simple models with a flavor-dependent global U(1)ℓ and a discrete ℤ2 symmetries to explain the anomalies in the measured anomalous magnetic dipole moments of muon and electron, (g − 2) μ,e , while simultaneously accommodating a dark matter ...

Toward high-precision values of the self energy of non-S states in hydrogen and hydrogen-like ions

, 2004
The method and status of a study to provide numerical, high-precision values of the self-energy level shift in hydrogen and hydrogen-like ions is described. Graphs of the self energy in hydrogen-like ions with nuclear charge number between 20 and 110 are

Learned Conformational Space and Pharmacophore Into Molecular Foundational Model

Advanced Science, Volume 13, Issue 17, 23 March 2026.
The Ouroboros model introduces two orthogonal modules within a unified framework that independently learn molecular representations and generate chemical structures. This design enables flexible optimization strategies for each module and faithful structure reconstruction without prompts or noise.

Quark and gluon contents of a lepton at high energies

Journal of High Energy Physics, 2022
In high-energy leptonic collisions, such as at a multi-TeV muon collider, the collinear splittings of the electroweak (EW) gauge bosons and leptons are the dominant phenomena, and the scattering processes should thus be formulated in terms of the EW ...

High precision hyperfine measurements in Bismuth challenge bound-state strong-field QED

Nature Communications, 2017
AbstractElectrons bound in highly charged heavy ions such as hydrogen-like bismuth 209Bi82+ experience electromagnetic fields that are a million times stronger than in light atoms. Measuring the wavelength of light emitted and absorbed by these ions is therefore a sensitive testing ground for quantum electrodynamical (QED) effects and especially the ...

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Extracting the chiral anomaly from e + e − → 3π

Journal of High Energy Physics
The strength of the interaction of three pions and a photon, F 3π is predicted by the axial anomaly in terms of the pion decay constant, a relation that is frequently used to constrain low-energy radiative processes involving pions, but only tested ...

Simple Atoms, Quantum Electrodynamics and Fundamental Constants

, 2003
This review is devoted to precision physics of simple atoms. The atoms can essentially be described in the framework of quantum electrodynamics (QED), however, the energy levels are also affected by the effects of the strong interaction due to the ...

Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.
