Symmetry-dependent topological phase transitions in PbTe layers
Daniely Bassanezi, Ernesto O. Wrasse, Tome M. Schmidt
By stacking PbTe layers there is a non-monotonic topological phase transition as a function of the number of monolayers. Based on first principles calculations we find that the pro…

Topological Nonsymmorphic Ribbons out of Symmorphic Bulk
Augusto L. Araújo, Ernesto O. Wrasse, Gerson J. Ferreira +1
States of matter with nontrivial topology have been classified by their bulk symmetry properties. However, by cutting the topological insulator into ribbons, the symmetry of the sy…
