Abstract:We study longitudinal magnetotransport in disorder-free cylindrical Weyl semimetal nanowires. Our theory includes a magnetic flux Φ piercing the nanowire and captures the finite curvature of the Fermi arc in the surface Brillouin zone through a boundary angle α. Electron backscattering by acoustic phonons via the deformation potential causes a finite resistivity which we evaluate by means of the semiclassical Boltzmann approach. We find that low-energy transport is dominated by surface states, where transport … Show more
