Chiral Anomaly in Non-Relativistic Systems: Berry Curvature and Chiral Kinetic Theory

نویسندگان

چکیده

Chiral anomaly and the novel quantum phenomena it induces have been widely studied for Dirac Weyl fermions. In most typical cases, Lorentz covariance is assumed thus linear dispersion relations are maintained. However, in realistic materials, such as semimetals, non-linear appear naturally. We develop a kinetic framework to study chiral fermions with dispersions by using methods of Wigner function semi-classical equations motion. this framework, sourced Berry monopoles momentum space could be enhanced or suppressed due windings around monopoles. Our results can help understand anomaly-induced transport non-relativistic systems.

Chiral kinetic theory.

We derive the nonequilibrium kinetic equation describing the motion of chiral massless particles in the regime where it can be considered classically. We show that the Berry monopole which appears at the origin of the momentum space due to level crossing is responsible for the chiral magnetic and vortical effects.

Consistent Chiral Kinetic Theory in Weyl Materials: Chiral Magnetic Plasmons.

We argue that the correct definition of the electric current in the chiral kinetic theory for Weyl materials should include the Chern-Simons contribution that makes the theory consistent with the local conservation of the electric charge in electromagnetic and strain-induced pseudoelectromagnetic fields. By making use of such a kinetic theory, we study the plasma frequencies of collective modes...

Lorentz invariance in chiral kinetic theory.

We show that Lorentz invariance is realized nontrivially in the classical action of a massless spin-1/2 particle with definite helicity. We find that the ordinary Lorentz transformation is modified by a shift orthogonal to the boost vector and the particle momentum. The shift ensures angular momentum conservation in particle collisions and implies a nonlocality of the collision term in the Lore...

The chiral anomaly from M theory

We argue that the chiral anomaly of N = 1 super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on G2 holonomy manifolds. We identify an angle of the G2 background dual to the anomalous U(1)R current in field theory. This angle is not an isometry of the metric and we therefore develop a theory of “massive isometry” to describe fluctuations about such ang...

Chiral Anomaly and Γ3π *

Measurement of the γ3π process has revealed a possible conflict with what should be a solid prediction generated by the chiral anomaly. We show that inclusion of appropriate energy-momentum dependence in the matrix element reduces the discrepancy. ∗ Research supported in part by the National Science Foundation.
