General formula of chiral anomaly for type-I and type-II Weyl semimetals

نویسندگان

چکیده

Weyl semimetals (WSMs) are classified into type-I and type-II, depending on the magnitudes of inclination cones. It is known that these WSMs show negative longitudinal magnetoresistance originating from chiral anomaly. Moreover, we have recently revealed type-II positive The in can be explained utilizing conventional formula anomaly, which does not term related to However, cannot explain both it. Therefore, this paper, derive general including cones order straightforwardly WSMs. Also, consider cases where a pair tilted same direction (positive tilt chirality) toward (or against) each other (negative investigate influence tilted. As result, find chirality, strongly affected by inclination. These results suggest estimate whether or using information their chirality

Electromagnetic Signatures of the Chiral Anomaly in Weyl Semimetals.

Weyl semimetals are predicted to realize the three-dimensional axial anomaly first discussed in particle physics. The anomaly leads to unusual transport phenomena such as the chiral magnetic effect in which an applied magnetic field induces a current parallel to the field. Here we investigate diagnostics of the axial anomaly based on the fundamental equations of axion electrodynamics. We find t...

Magnetic torque anomaly in the quantum limit of Weyl semimetals

Electrons in materials with linear dispersion behave as massless Weyl- or Dirac-quasiparticles, and continue to intrigue due to their close resemblance to elusive ultra-relativistic particles as well as their potential for future electronics. Yet the experimental signatures of Weyl-fermions are often subtle and indirect, in particular if they coexist with conventional, massive quasiparticles. H...

Weyl-titchmarsh Type Formula for Hermite Operator with Small Perturbation

Small perturbations of the Jacobi matrix with weights √ n and zero diagonal are considered. A formula relating the asymptotics of polynomials of the first kind to the spectral density is obtained, which is analogue of the classical Weyl-Titchmarsh formula for the Schrödinger operator on the half-line with summable potential. Additionally a base of generalized eigenvectors for ”free” Hermite ope...
