Zhang et al. Reply: The preceding Comment [1] uses an incorrect set of equilibrium states to analyze transport and arrives at a wrong interpretation of the spinor dispersion relation used in our Letter [2].The spinor energy-momentum dispersion introduced in our Letter [see Eq. (1)], or Eq. (2) of the Comment,

We review the current situation in the theory of superconducting and transport properties of MgB2. First principle calculations of of the electronic structure and electron-phonon coupling are discussed and compared with the experiment. We also present a brief description of the multiband effects in superconductivity and transport, and how these manifest themselves in MgB2. We also mention some yet open questions.
