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.

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.

Nonlinear chiral forms in the Sen formulation

open access: yesEuropean Physical Journal C: Particles and Fields
The Sen formulation for chiral (2p)-form in $$4p+2$$ 4 p + 2 dimensions describes a system with two separate sectors, one is physical while the other is unphysical. Each contains a chiral form and a metric.

Finite density two color chiral perturbation theory revisited

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We revisit two-color, two-flavor chiral perturbation theory at finite isospin and baryon density. We investigate the phase diagram obtained varying the isospin and the baryon chemical potentials, focusing on the phase transition occurring when the two ...

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 ...

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.

Chiral condensate in nuclear matter beyond linear density using chiral Ward identity*

open access: yesEPJ Web of Conferences, 2012
We discuss density corrections of the chiral condensate up to a NLO order using the chiral Ward identity and an in-medium chiral perturbation theory.

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 ...

Partition Function of Chiral Boson on 2-Torus from Floreanini-Jackiw Lagrangian [PDF]

open access: yes, 2013
We revisit the problem of quantizing a chiral boson on a torus. The conventional approach is to extract the partition function of a chiral boson from the path integral of a non-chiral boson. Instead we compute it directly from the chiral boson Lagrangian
