Kekulé distortions in graphene on cadmium sulfide
Yonatan Betancur-Ocampo, Santiago Galván y García, Samuel Tehuacanero Nuñez +3
The deposition of a two-dimensional material on the surface of a three-dimensional crystal can generate superlattices with electronic properties modified through the proximity spin…
Atomically thin current pathways in graphene through Kekulé-O engineering
Santiago Galván y García, Yonatan Betancur-Ocampo, Francisco Sánchez-Ochoa +1
We demonstrate that the current flow in graphene can be guided on atomically thin current pathways by means of the engineering of Kekulé-O distortions. A grain boundary in these di…
Spin-valley locking in Kekulé-distorted graphene with Dirac-Rashba interactions
David A. Ruiz-Tijerina, Jesús Arturo Sánchez-Sánchez, Ramon Carrillo-Bastos +2
The joint effects of Kekulé lattice distortions and Rashba-type spin-orbit coupling on the electronic properties of graphene are explored. We modeled the position dependence of the…
Generalized Hamiltonian for Kekulé graphene and the emergence of valley-cooperative Klein tunneling
Santiago Galván y García, Thomas Stegmann, Yonatan Betancur-Ocampo
We introduce a generalized Hamiltonian describing not only all topological phases observed experimentally in Kekulé graphene (KekGr) but predicting also new ones. These phases show…
Hidden invariance of the free classical particle
Santiago García
A formalism describing the dynamics of classical and quantum systems from a group theoretical point of view is presented. We apply it to the simple example of the classical free pa…
