Topological insulating phases in mono and bilayer graphene
Alberto Cortijo, Adolfo G. Grushin, Maria A. H. Vozmediano
We analyze the influence of different quadratic interactions giving rise to time reversal invariant topological insulating phases in mono and bilayer graphene. We make use of the e…
Renormalization of Coulomb interaction in graphene: computing observable quantities
Fernando de Juan, Adolfo G. Grushin, Maria A. H. Vozmediano
We address the computation of physical observables in graphene in the presence of Coulomb interactions of density-density type modeled with a static Coulomb potential within a quan…
Tunable Casimir repulsion with three dimensional topological insulators
Adolfo G. Grushin, Alberto Cortijo
In this Letter, we show that switching between repulsive and attractive Casimir forces by means of external tunable parameters could be realized with two topological insulator plat…
