Connecting the dots: Time-reversal symmetric Weyl Semimetals with tunable Fermi arcs
Vatsal Dwivedi, Srinidhi T Ramamurthy
We propose a one-parameter family of noninteracting lattice models for Weyl semimetals with 4 Weyl nodes and tunable Fermi arcs. These 2-band model Hamiltonians are time-reversal s…

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…
