Query: Weak measurement of quantum superposition states in graphene   We employ a weak measurement approach to demonstrate the very existence of
the photoexcited interband superposition states in intrinsic graphene. We
propose an optical two-beam setup where such measurements are possible and
derive an explicit formula for the differential optical absorption that
contains a signature of such states. We provide an interpretation of our
results in terms of a non-Markovian weak measurement formalism applied to the
pseudospin degree of freedom coupled with an electromagnetic wave.
