  We investigate the effect of an in-plane AC electric field coupled to
electrons in the honeycomb lattice and show that it can be used to manipulate
the Dirac points of the electronic structure. We find that the position of the
Dirac points can be controlled by the amplitude and the polarization of the
field for high frequency drivings, providing a new platform to achieve their
merging, a topological transition which has not been observed yet in electronic
systems. Importantly, for lower frequencies we find that the multi-photon
absorptions and emissions processes yield the creation of additional pairs of
Dirac points. This provides an additional method to achieve the merging
transition by just tuning the frequency of the driving. Our approach, based on
Floquet formalism, is neither restricted to specific choice of amplitude or
polarization of the field, nor to a low energy approximation for the
Hamiltonian.
