Query: Direction dependent giant optical conductivity in 2D \textit{semi}-Dirac
  materials   We show that the gap parameter in \textit{semi}-Dirac material induces a
large degree of sensitivity for inter-band optical conductivity with respect to
the polarization direction. The optical conductivity reveals an abruptly large
value at a certain frequency for light along a particular polarization
direction while it is significantly suppressed along the direction orthogonal
to the former. The direction-dependent optical conductivity may, in turn, be
used to uniquely predict the dispersive nature of the 2D \textit{semi}-Dirac
materials, in addition to other possible applications in the field of
transparent conductors.
