Query: Raman Scattering as a Selective Probe of Chiral Electronic Excitations
  in Bilayer Graphene   We report a symmetry resolved electronic Raman scattering (ERS) study of a
bilayer graphene device under gate voltage. We show that the ERS continuum is
dominated by interband chiral excitations of $A_{2}$ symmetry and displays a
characteristic Pauli-blocking behavior similar to the monolayer case.
Crucially, we show that non-chiral excitations make a vanishing contribution to
the Raman cross-section due to destructive interference effects in the Raman
amplitude matrix elements. This is in a marked contrast to optical absorption
measurements and opens interesting venues for the use of Raman scattering as a
selective probe of chiral degrees of freedom in topological matter and other 2D
crystals.
