Author(s): E. V. Gorbar, V. A. Miransky, I. A. Shovkovy, and P. O. Sukhachov The existence of the surface Fermi arc states is a signature property of the Weyl semimetals. In view of their one-dimensional chiral nature, one might naively expect that the corresponding surface transport is nondissipative. In a drastic contrast to such an expectation, the authors show here that the dynamics of the chiral surface states is dissipative in semimetals. In the presence of impurities, the origin of the dissipation is the scattering of surface Fermi arc states into the bulk of the semimetal. The gapless spectrum of the bulk states in semimetals is the key feature that allows such processes to happen. By taking into account all scattering processes, the authors perform a model calculation of the electric conductivity of the surface Fermi arc states. [Phys. Rev.
