| Summary: | The topological crystalline Insulators (TCI) are topological materials with metallic surface states protected by a symmetry given by the crystalline structure, and not by the Time reversal one as in the usual topological insulators. These insulators, whose band structures are classified by new topological invariants, are the counterpart of the topological insulators but without the spin-orbit coupling being the principal aspect. In this work, a theoretical study on the present topological invariants is shown by means of experimental measurements in monocrystals of (Pb1-xSnx)Te which are grown for this project. Particularly, it is desired to understand the evolution with magnetic field of the Landau energy levels of this kind of topological insulators. |
