Intrinsic negative magnetoresistance from the chiral anomaly of multifold fermions [PDF]

open access: yesNature Communications
The 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

Giant negative magnetoresistance induced by the chiral anomaly in individual Cd3As2 nanowires [PDF]

open access: yesNat Commun, 2015
Cd3As2 is a newly booming Dirac semimetal with linear dispersion along all three momentum directions and can be viewed as 3D analog of graphene. As breaking of either time reversal symmetry or spatial inversion symmetry, the Dirac semimetal is believed ...

Quantized chiral anomaly materials cloak [PDF]

open access: yesScientific Reports, 2017
Chiral 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 ...

Observation of vortex-string chiral modes in metamaterials [PDF]

open access: yesNature Communications
As 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.

Chiral anomalies in 3D spin-orbit coupled metals: electrical, thermal, and gravitational anomaly [PDF]

open access: yes, 2023
The discovery of a chiral anomaly in Weyl semimetals, the non-conservation of chiral charge and energy across two opposite chirality Weyl nodes, has sparked immense interest in understanding its impact on various physical phenomena. Here, we demonstrate the existence of electrical, thermal, and gravitational quantum chiral anomalies in 3D spin-orbit ...

Spectroscopic Manifestations and Implications for Catalysis of Quasi‐d10 Configurations in Formal Gold(III) Complexes

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Through the interplay of X‐ray spectroscopy and computational analysis, we show that gold +I and +III complexes, despite their physically distinct electronic structures, tend to activate substrates to similar extents. We focus in particular on the role of electron‐sharing covalency of the metal‐ligand bonds and provide an explanation for the often ...

Anomalies on Orbifolds [PDF]

open access: yes, 2001
We discuss the form of the chiral anomaly on an S1/Z2 orbifold with chiral boundary conditions. We find that the 4-divergence of the higher-dimensional current evaluated at a given point in the extra dimension is proportional to the probability of ...

Electric quantum oscillations in Weyl semimetals

open access: yesPhysical Review Research, 2021
Electronic transport in Weyl semimetals is quite extraordinary due to the topological property of the chiral anomaly generating the charge pumping between two distant Weyl nodes with opposite chiralities under parallel electric and magnetic fields. Here,

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, EarlyView., 2023
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.

Magneto-vortical effect in strongly coupled plasma

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Based on a holographic model incorporating both the chiral anomaly and the gravitational anomaly, we study the effect of magneto-vortical coupling on the transport properties of a strongly coupled plasma. The focus of present work is on the generation of
