Abstract: In this talk I will consider a two-dimensional massless Dirac operator coupled to a magnetic field B and an electric potential V growing at infinity. I will present results concerning the characterization of the spectrum of the resulting operator H in terms of the relation between B and V at infinity. In particular, we find a sharp condition for the discreteness of the spectrum of H and a regime with dense pure point spectrum. This is joint work with Josef Mehringer.
