  In this work we describe semiclassical states in graphene under a constant
perpendicular magnetic field by constructing coherent states in the
Barut-Girardello sense. Since we want to keep track of the angular momentum,
the use of the symmetric gauge and polar coordinates seemed the most logical
choice. Different classes of coherent states are obtained by means of the
underlying algebra system, which consists of the direct sum of two
Heisenberg-Weyl algebras. The most interesting cases are a kind of partial
coherent states and the coherent states with a well-defined total angular
momentum.
