In our theoretical research, we investigated how the interaction of graphene with a bi-circular laser field modifies the electronic band structure near the Dirac points. The Dirac-Weyl-Majorana equation, solved using the Floquet theory and the Fourier decomposition, was used to determine the currents induced in graphene. The results show the presence of characteristic current structures with non-zero topological charges, which in turn lead to the generation of high-order harmonics with specific polarization and topological properties.
