DESCRIPTION:Mass and chirality inversion of a Dirac cone pair in Stückelbe
 rg interferometry\nLih-King LIM (Institut d'Optique\, Palaiseau)\nThe aim 
 of the present work is to show that a Stückelberg interferometer made of 
 two massive Dirac cones can reveal information on band eigenstates such as
  the chirality and mass sign of the cones. For a given spectrum featuring 
 two gapped cones\, we propose several low-energy Hamiltonians differing by
  their eigenstates properties. The corresponding inter-band transition pro
 bability is affected by such differences in its interference fringes being
  shifted by a new phase of geometrical origin. This phase can be a useful 
 bulk probe for cold atoms in topological optical lattices.
