Optical conductivity of disordered graphene beyond the Dirac cone approximation
Shengjun Yuan, Rafael Roldán, Hans De Raedt +1
In this paper we systemically study the optical conductivity and density of states of disorded graphene beyond the Dirac cone approximation. The optical conductivity of graphene is…
Landau Level Spectrum of ABA- and ABC-stacked Trilayer Graphene
Shengjun Yuan, Rafael Roldán, Mikhail I. Katsnelson
We study the Landau level spectrum of ABA- and ABC-stacked trilayer graphene. We derive analytic low energy expressions for the spectrum, the validity of which is confirmed by comp…
Excitation spectrum and high energy plasmons in single- and multi-layer graphene
Shengjun Yuan, Rafael Roldán, Mikhail I. Katsnelson
In this paper we study the excitation spectrum of single- and multi-layer graphene beyond the Dirac cone approximation. The dynamical polarizability of graphene is computed using a…
Suppression of anharmonicities in crystalline membranes by external strain
Rafael Roldán, Annalisa Fasolino, Kostyantyn V. Zakharchenko +1
In practice, physical membranes are exposed to a certain amount of external strain (tension or compression), due to the environment where they are placed. As a result, the behavior…
