Optical far-infrared properties of a graphene monolayer and multilayer
We analyze the features of the graphene mono- and multilayer reflectance in the far-infrared region as a function of frequency, temperature, and carrier density taking the intraband conductance andExpand

Electron-lattice kinetics of metals heated by ultrashort laser pulses
We propose a kinetic model of transient nonequilibrium phenomena in metals exposed to ultrashort laser pulses when heated electrons affect the lattice through direct electron-phonon interaction. ThisExpand

Symmetry constraints on phonon dispersion in graphene
Abstract We calculate the phonon dispersion for graphene with interactions between the first, second, and third nearest neighbors in the framework of the Born–von Karman model taking into account theExpand

Phonon dispersion in graphene
Taking into account the constraints imposed by the lattice symmetry, we calculate the phonon dispersion for graphene with interactions between the first and second nearest neighbors. We show thatExpand
