Weyl Fermions

Quantum Oscillations from Fermi arc surface states of Weyl and Dirac semimetals. arXiv:1402.6342 (with Drew Potter and Itamar Kimchi) Nature Communications 2014.

Weyl semimetals have very unusual surface states that take the form of `Fermi arcs'. A standard probe of Fermi surfaces is quantum oscillations - and these surface states must display an unusual  signatures given that Fermi arcs cannot on their own give rise to closed orbits. Predictions for quantum oscillations in thin films of both Weyl and the recently discovered Dirac semimetals are made.
