This paper gives a theoretical formulation of the electromagnetic response of the quasi-two-dimensional crystals suitable for investigation of optical activity and polariton modes. The response to external electromagnetic field is described by curren

In this paper we clarify the nature of π and π+σ electron excitations in pristine graphene. We clearly demonstrate the continuous transition from single particle to coll

We investigate electron tunneling in a system consisting of two curved metal surfaces separated by insulator or vacuum. In particular, we calculate the modifications of the tunneling barrier due to dynamical screening, i.e., interaction with charge f

The spectra of electronic excitations in graphene are calculated using first principles time-dependent density functional theory formalism, and used to obtain π and π+σ plasmon dispersion curves. The spectra and dispersion are in excellent agreeme
