Monolayer graphite films, or graphene, have quasiparticle excitations that can be described by (2+1)-dimensional Dirac theory. We demonstrate that this produces an unconventional form of theâ€¦ (More)

The intensity as well as position in energy of the absorption lines in the infrared conductivity of graphene, both exhibit features that are directly related to the Dirac nature of itsâ€¦ (More)

The quantum magnetic oscillations are studied for planar condensed-matter systems with a linear, Dirac-like spectrum of quasiparticle excitations. We derive analytical expressions for magneticâ€¦ (More)

Recent experiments have proven that the quasiparticles in graphene obey a Dirac equation. Here we show that microwaves are an excellent probe of their unusual dynamics. When the chemical potential isâ€¦ (More)

The latest experiments have confirmed the theoretically expected universal value Ï€e/2h of the ac conductivity of graphene and have revealed departures of the quasiparticle dynamics from predictionsâ€¦ (More)

We consider the relationship between the tight-binding Hamiltonian of the two-dimensional honeycomb lattice of carbon atoms with nearest neighbor hopping only and the 2 + 1 dimensional Hamiltonian ofâ€¦ (More)

We derive a finite temperature time-dependent effective theory for the phase Î¸ of the pairing field, which is appropriate for a 2D conducting electron system with non-retarded d-wave attraction. Asâ€¦ (More)

This article gives a contemporary and to some extent pedagogical review of the current theoretical understanding of the formation of the superconducting state in metallic systems with a variableâ€¦ (More)

Edge states on a finite width graphene ribbon in a magnetic field are studied in the framework of low-energy effective theory that takes into account the possibility of quantum Hall ferromagnetismâ€¦ (More)

It is shown that in 2D system of the fermions with simplest indirect boson-induced attraction (through the Einstein phonon exchange as an example) along with the normal and superconducting phasesâ€¦ (More)
