Single-particle excitations in disordered Weyl fluids
Single-particle excitations in disordered Weyl fluids
The authors determine the fate of single-particle Weyl excitations in the presence of short-range disorder. Using analytic and numerical methods, the authors show that weakly disordered Weyl excitations are not ballistic and acquire an exponentially small but nonzero quasiparticle lifetime due to rare regions of the random disorder potential.
