Quantized chiral anomaly materials cloak. [PDF]
Sci Rep, 2017 AbstractChiral anomaly materials (CAM, e.g., axion insulator, topological insulator and some of Weyl semimetal) are new states of quantum matter. Anomalous Hall effect can occur in CAM, the anomalous Hall effect is closely related to the topological magneto-electric effect, i.e., when an electric field is applied to CAM, not only the electric field is ...

Hydrodynamic Manifestations of Gravitational Chiral Anomaly. [PDF]
Physical Review Letters, 2022 The conservation of an axial current modified by the gravitational chiral anomaly implies the universal transport phenomenon (kinematical vortical effect) dependent solely on medium vorticity and acceleration, but not dependent explicitly on its ...

Chiral Anomaly Beyond Lorentz Invariance [PDF]
Physical Review D, 2007 The chiral anomaly in the context of an extended standard model with minimal Lorentz invariance violation is studied. Taking into account bounds from measurements of the speed of light, we argue that the chiral anomaly and its consequences are general ...

Chiral anomaly and quasi-classical planar Hall effect in Weyl semimetals [PDF]
Physical Review Letters, 2017 In condensed matter physics, the term "chiral anomaly" implies the violation of the separate number conservation laws of Weyl fermions of different chiralities in the presence of parallel electric and magnetic fields.

Observation of the Chiral-Anomaly-Induced Negative Magnetoresistance in 3D Weyl Semimetal TaAs [PDF]
Physical Review X, 2015 Weyl semimetal is the three-dimensional analog of graphene. According to quantum field theory, the appearance of Weyl points near the Fermi level will cause novel transport phenomena related to chiral anomaly.

Observation of vortex-string chiral modes in metamaterials [PDF]
Nature CommunicationsAs hypothetical topological defects in the geometry of spacetime, vortex strings could have played many roles in cosmology, and their distinct features can provide observable clues about the early universe’s evolution.

Bootstrapping the chiral anomaly at large Nc [PDF]
Journal of High Energy Physics, 2023 The bootstrap approach (demanding consistency conditions to scattering amplitudes) has shown to be quite powerful to tightly constrain gauge theories at large Nc.

Parity-violating CFT and the gravitational chiral anomaly [PDF]
Physical Review D, 2023 We illustrate how the Conformal Ward Identities (CWI) and the gravitational chiral anomaly completely determine the structure of the $\langle TTJ_{5}\rangle$ (graviton-graviton-chiral gauge current) correlator in momentum space. This analysis extends our
