Double-layer graphene and topological insulator thin-film plasmons
Rosario E. V. Profumo, Reza Asgari, Marco Polini +1
We present numerical and analytical results for the optical and acoustic plasmon collective modes of coupled massless-Dirac two-dimensional electron systems. Our results apply to t…
The tunneling density-of-states of interacting massless Dirac fermions
A. Principi, Marco Polini, Reza Asgari +1
We calculate the tunneling density-of-states (DOS) of a disorder-free two-dimensional interacting electron system with a massless-Dirac band Hamiltonian. The DOS exhibits two main…
Effective screening and the plasmaron bands in Graphene
Andrew L. Walter, Aaron Bostwick, Ki-Joon Jeon +10
Electron-plasmon coupling in graphene has recently been shown to give rise to a "plasmaron" quasiparticle excitation. The strength of this coupling has been predicted to depend on…
Many-body effects in van der Waals-Casimir interaction between graphene layers
Jalal Sarabadani, Ali Naji, Reza Asgari +1
Van der Waals-Casimir dispersion interactions between two apposed graphene layers, a graphene layer and a substrate, and in a multilamellar graphene system are analyzed within the…
Topological electric current from time-dependent elastic deformations in graphene
Abolhassan Vaezi, Nima Abedpour, Reza Asgari +2
We show the possibility of inducing an edge charge current by applying time-dependent strain in gapped graphene samples preserving time reversal symmetry. We demonstrate that this…
Strains and pseudo-magnetic fields in circular graphene rings
Nima Abedpour, Reza Asgari, F. Guinea
We demonstrate that circular graphene ring under a shear stress displays strong pseudo-magnetic fields. We calculate the pseudo-magnetic field both from continuum elasticity theory…
