Chiral anomaly in (1+1) dimensions revisited: complementary kinetic perspective and universality [PDF]

open access: yesJ. Phys. Soc. Jpn. 93, 114006 (2024), 2022
We reinvestigate the classic example of the chiral anomaly in (1+1) dimensional spacetime. By reviewing the derivation of charge conservation using the semiclassical Boltzmann equation, we show that chiral anomalies could emerge in (1+1) dimensions without Berry curvature corrections to the kinetic theory.

Review of experiments on the chiral anomaly in Dirac-Weyl semimetals [PDF]

open access: yesNature Review Physics 3, 394 (2021), 2020
We provide a review of recent experimental results on the chiral anomaly in Dirac/Weyl semimetals. After a brief introduction, we trace the steps leading to the prediction of materials that feature protected 3D bulk Dirac nodes. The chiral anomaly is presented in terms of charge pumping between the chiral Landau levels of Weyl fermions in parallel ...

On the Bose symmetry and the left- and right-chiral anomalies

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
It is generally assumed that in order to preserve Bose symmetry in the left- (or right-chiral) current it is necessary to equally distribute the chiral anomaly between the vectorial and the axial Ward identities, requiring the use of counterterms to ...

Invariant Regularization of Supersymmetric Chiral Gauge Theory [PDF]

open access: yes, 1998
We formulate a manifestly supersymmetric gauge covariant regularization of supersymmetric chiral gauge theories. In our scheme, the effective action in the superfield background field method above one-loop is always supersymmetric and gauge invariant ...

Hamiltonian approach to the torsional anomalies and its dimensional ladder [PDF]

open access: yesPhys. Rev. B 101, 165201 (2020), 2019
Torsion can cause various anomalies in various dimensions, including the $\left(3+1\right)$-dimensional $[(3+1)D]$ Nieh-Yan anomaly, the $\left(2+1\right)$D Hughes-Leigh-Fradkin (HLF) parity anomaly, and the $\left(3+1\right)$D, $\left(1+1\right)$D chiral energy-momentum anomaly. We study these anomalies from the Hamiltonian approach.

Chiral waves on the Fermi-Dirac sea: Quantum superfluidity and the axial anomaly

open access: yesNuclear Physics B, 2021
We show that as a result of the axial anomaly, massless fermions at zero temperature define a relativistic quantum superfluid. The anomaly pole implies the existence of a gapless Chiral Density Wave (CDW), i.e.

On the associativity of 1-loop corrections to the celestial operator product in gravity

open access: yesJournal of High Energy Physics, 2023
The question of whether the holomorphic collinear singularities of graviton amplitudes define a consistent chiral algebra has garnered much recent attention.

Cancellation of Conformal and Chiral Anomalies in $N \geq 5$ supergravities [PDF]

open access: yesPhys. Rev. D 95, 041701 (2017), 2016
A cancellation of conformal anomalies in d=4 for the $C^2+\bar C^2$ and of chiral anomalies for the $C^2-\bar C^2$ is known in N-extended supergravities with $N \geq 5$. We propose an explanation of these cancellations using supersymmetry and dimension of linearized chiral superfields.

Metal‐organic framework derived porous structures towards lithium rechargeable batteries

open access: yesEcoMat, Volume 5, Issue 2, February 2023., 2023
In this review, we discuss the characteristics of metal‐organic frameworks (MOFs) applied to lithium storage devices containing Li‐ion, Li‐sulfur, Li‐metal, and Li‐O2. We summarize the origin, nomenclature, and synthesis method of MOFs, and report on recent studies in which MOFs and MOF‐derived materials are applied to lithium rechargeable batteries ...

Anomaly cancellation in effective supergravity theories from the heterotic string: Two simple examples

open access: yesNuclear Physics B, 2018
We use Pauli–Villars regularization to evaluate the conformal and chiral anomalies in the effective field theories from Z3 and Z7 compactifications of the heterotic string without Wilson lines.
