Query: Evidence of both surface and bulk Dirac bands in ZrSiS and the
  unconventional magnetoresistance   The unconventional magnetoresistance of ZrSiS single crystals is found
unsaturated till the magnetic field of 53 T with the butterfly shaped angular
dependence. Intense Shubnikov-de Haas oscillations resolve a bulk Dirac cone
with a nontrivial Berry phase, where the Fermi surface area is 1.80*10^-3
{\AA}-2 and reaches the quantum limit before 20 T. Angle resolved photoemission
spectroscopy measurement reveals an electronic state with the two-dimensional
nature around the X point of Brillouin zone boundary. By integrating the
density functional theory calculations, ZrSiS is suggested to be a Dirac
material with both surface and bulk Dirac bands.
