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...
متن کاملInterference Phenomena, Chiral Bosons and Lorentz Invariance
The concept of interference phenomena in quantum field theory is an analogy with Young's double slit experiment. It has been studied over the last few years, in various dimensions, in the light of the soldering formalism introduced by Stone to fusion two opposite manifestations of chirality. Firstly, we have studied the theory of gauged chiral bosons and proposed a new general theory that encom...
متن کاملInstantons, Scale Invariance and Lorentz Invariance in Matrix Theory
In this paper we consider features of graviton scattering in Matrix theory compactified on a 2-torus. The features which interest us can only be determined by nonperturbative effects in the corresponding 2+1 dimensional super Yang Mills theory. We show that the superconformal symmetry of strongly coupled Super Yang Mills Theory in 2 + 1 dimensions almost determines low energy, large impact para...
متن کاملChiral 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.
متن کاملConsistent 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...
