Abstract

We formulate and apply a theory of electron-phonon interactions for the surface state of a strong topological insulator. Phonons are modelled using an isotropic elastic continuum theory with stress-free boundary conditions and interact with the Dirac surface fermions via the deformation potential. We discuss the temperature dependence of the quasi-particle lifetime in photoemission and of the surface resistivity. ; Comment: 5 pages, 3 figures
