Intrinsic negative magnetoresistance from the chiral anomaly of multifold fermions [PDF]
Nature CommunicationsThe chiral anomaly - a hallmark of chiral spin-1/2 Weyl fermions - is an imbalance between left- and right-moving particles that underpins phenomena such as particle decay and negative longitudinal magnetoresistance in Weyl semimetals. The discovery that

Probing charge pumping and relaxation of the chiral anomaly in a Dirac semimetal. [PDF]
Sci Adv, 2021 Using time domain magneto-THz spectroscopy, chiral anomaly in a Dirac semimetal is unambiguously resolved in a noncontact manner. The linear band crossings of 3D Dirac and Weyl semimetals are characterized by a charge chirality, the parallel or ...

Signatures of the Adler-Bell-Jackiw chiral anomaly in a Weyl fermion semimetal. [PDF]
Nat Commun, 2016 Weyl semimetals provide the realization of Weyl fermions in solid-state physics. Among all the physical phenomena that are enabled by Weyl semimetals, the chiral anomaly is the most unusual one.

Chiral anomaly in Euler fluid and Beltrami flow [PDF]
Journal of High Energy Physics, 2022 We show that barotropic flows of a perfect, charged, classical fluid exhibit an anomaly analogous to the chiral anomaly known in quantum field theories with Dirac fermions. A prominent effect of the chiral anomaly is the transport electric current in the

The discovery of dynamic chiral anomaly in a Weyl semimetal NbAs. [PDF]
Nat Commun, 2020 The experimental discovery of Weyl semimetals offers unprecedented opportunities to study Weyl physics in condensed matters. Unique electromagnetic response of Weyl semimetals such as chiral magnetic effect has been observed and presented by the axial θ ...

Chiral anomaly induces superconducting baryon crystal [PDF]
Journal of High Energy Physics, 2022 It was previously shown within chiral perturbation theory that the ground state of QCD in a sufficiently large magnetic field and at nonvanishing, but not too large, baryon chemical potential is a so-called chiral soliton lattice.

Parity-odd 3-point functions from CFT in momentum space and the chiral anomaly [PDF]
European Physical Journal C: Particles and Fields, 2023 We illustrate how the Conformal Ward Identities (CWI) in momentum space for parity-odd correlators determine the structure of a chiral anomaly interaction, taking the example of the VVA (vector/vector/axial-vector) and AAA correlators in momentum space ...

Nonlinear chiral transport from holography
Journal of High Energy Physics, 2019 Nonlinear transport phenomena induced by the chiral anomaly are explored within a 4D field theory defined holographically as U(1) V × U(1) A Maxwell-Chern-Simons theory in Schwarzschild-AdS 5.

Nuclear Physics B, 2019 It was found that s-wave scattering of chiral fermion off dilaton black-hole when studied with a model generated from the chiral Schwinger model with standard Jackiw-Rajaraman type of anomaly provided information non preserving result.

Thermal and gravitational chiral anomaly induced magneto-transport in Weyl semimetals [PDF]
Physical Review Research, 2020 Quantum anomalies in Weyl semimetal (for either E·B≠0 or ∇T·B≠0) leads to chiral charge and energy pumping between the opposite chirality nodes. This results in chiral charge and energy imbalance between the Weyl nodes which manifests in several ...
