  Dirac carriers in graphene are commonly characterized by a pseudospin degree
of freedom, arising from the degeneracy of the two inequivalent sublattices.
The inherent chirality of the quasiparticles leads to a topologically
non-trivial band structure, where the in-plane component of sublattice spin and
momentum are intertwined. Equivalently, sublattice imbalance is intimately
connected with angular momentum, inducing a torque of opposite sign at each
Dirac point. In this work we develop an intuitive picture that associates
sublattice spin and winding number with angular momentum. We develop a
microscopic perturbative model to obtain the finite angular momentum
contributions along the main crystallographic directions. Our results can be
employed to determine the angular dependence of the g-factor and of light
absorption in honeycomb bipartite structures.
