abstract

  • We investigate the validity of Huygens' principle for forward propagation in the massless Dirac-Weyl equation. The principle holds for odd space dimension n, while it is invalid for even n. We explicitly solve the cases n = 1, 2 and 3 and discuss generic n. We compare with the massless Klein-Gordon equation and comment on possible generalizations and applications.
