Chiral kinetic theory and anomalous hydrodynamics in even spacetime dimensions
Vatsal Dwivedi, Michael Stone
We study the hydrodynamics of a gas of noninteracting Weyl fermions coupled to the electromagnetic field in spacetime dimensions using the chiral kinetic theory, whi…
Wigner translations and the observer-dependence of the position of masslesss spinning particles
Michael Stone, Vatsal Dwivedi, Tianci Zhou
The Wigner little group for massless particles is isomorphic to the Euclidean group . Applied to momentum eigenstates, or to infinite plane waves, the Euclidean "Wigne…
Berry Phase, Lorentz Covariance, and Anomalous Velocity for Dirac and Weyl Particles
Michael Stone, Vatsal Dwivedi, Tianci Zhou
We consider the relation between spin and the Berry-phase contribution to the anomalous velocity of massive and massless Dirac particles. We extend the Berry connection that depend…
Classical chiral kinetic theory and anomalies in even space-time dimensions
Vatsal Dwivedi, Michael Stone
We propose a classical action for the motion of massless Weyl fermions in a background gauge field in (2N+1)+1 spacetime dimensions. We use this action to derive the collisionless…
A Classical Version of the Non-Abelian Gauge Anomaly
Michael Stone, Vatsal Dwivedi
We show that a version of the covariant gauge anomaly for a 3+1 dimensional chiral fermion interacting with a non-Abelian gauge field can be obtained from the classical Hamiltonian…
