Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

The Changes in Properties of Hadrons in Nuclei and Nuclear Matter [PDF]

open access: yes, 1995
The changes of hadron properties in dense and/or hot matter are discussed in terms of effective chiral Lagrangians with the parameters of the theory scaled in a simple way.

Hard thermal loops and chiral Lagrangians [PDF]

open access: yesPhysical Review D, 1998
Chiral symmetry is used as the guiding principle to derive hard thermal loop effects in chiral perturbation theory. This is done by using a chiral invariant background field method for the non-linear sigma model and the Wess-Zumino-Witten lagrangian, with and without external vector and axial vector sources.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

New classes of summable Skyrmions

open access: yes, 1993
We introduce two new classes of summable Skyrmions. The Lagrangians they originate from are explicitely constructed. We also analyse how some models could be solve. Exact solutions are found for Skyrme-like toy models.Comment: 9 pages, revtex v3, EP-CPTh.

Chiral Magnetism of the Nucleon [PDF]

open access: yes, 2002
We study the quark mass expansion of the magnetic moments of the nucleon in a chiral effective field theory including nucleons, pions and delta resonances as explicit degrees of freedom.

Quantum Anomalies in Condensed Matter

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

The dual properties of chiral and isospin asymmetric dense quark matter formed of two-color quarks

open access: yesJournal of High Energy Physics, 2020
In this paper the phase structure of dense baryon matter composed of u and d quarks with two colors has been investigated in the presence of baryon μ B , isospin μ I and chiral isospin μ I5 chemical potentials in the framework of Nambu-Jona-Lasinio model

An Algebraic Roadmap of Particle Theories

open access: yesAnnalen der Physik, Volume 537, Issue 4, April 2025.
Algebraic models of particle physics are often met with recurring obstacles. An ideal algebraic model should ‘1e conform to the Coleman‐Mandula theorem, ‘2e evade familiar fermion doubling problems, ‘3e naturally explain the Standard Model's chirality, ‘4e exclude B‐L gauge symmetry at low energy, and ‘5e explain the existence of three generations ...

Visible GeV ALP from TeV Vector‐Like Leptons

open access: yesFortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.
