Weyl semi-metals exhibit low energy excitations in their band structure for which the effective Hamiltonian resembles that of Weyl fermions. In condensed matter, the effective Weyl Hamiltonian can be tilted in momentum space, and when it's over-tilted the system is called a type II Weyl semi-metal. In this talk we describe the response of such a system to a magnetic or axial pseudo-magnetic field. We then predict that due to the nature of the chiral Landau level resulting from either a magnetic or a pseudo-magnetic field, the optical conductivity can be utilized to detect a type II phase in the semi-metal, and deduce the direction of the tilt.
