Abstract
Here we study a simple continuous medium - magnetized plasma - that possesses Weyl points which arise at the linear crossing between longitudinal plasmonic modes and transverse helical modes. The topological properties of this medium will be characterized by a first principles method. Specifically, a photonic Green function formalism will be used in order to calculate gap Chern numbers of band gaps located around the Weyl points, which will determine the topological charge of these three-dimensional linear degeneracies. The application of this method is discussed below.
